YSK - for all the things that can make your life easier!

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with YSK.

All posts must begin with YSK. If you're a Mastodon user, then include YSK after @youshouldknow. This is a community to share tips and tricks that will help you improve your life.



Rule 2- Your post body text must include the reason "Why" YSK:

**In your post's text body, you must include the reason "Why" YSK: It’s helpful for readability, and informs readers about the importance of the content. **



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-YSK posts.

Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you harass or discriminate against any individual member, you will be removed.

If you are a member, sympathizer or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- The majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

Why YSK: If you want to make Lemmy a more accessible place for all, you need to know how to add labels (aka: "alt text") to embedded images

As many of you are already aware, you can embed images in comments using the following markdown: ![](https://example.com/image.jpg).

That works, but the image will be left unlabeled which leaves screenreader users out of the conversation. This may seem like a theoretical problem, but it's not -- Lemmy already has an active blind community: https://rblind.com/

So, here's what you can do to add labels when embedding images:

![Earth viewed from the Moon](https://example.com/image.jpg)

That's it! Any text within the [] becomes "alt text", which is what screenreaders use for describing images. It's a small thing, but it makes a world of difference.

Remember: Reddit took something from many of us here. For some, it was a mobile app. For others, it was the ability to operate their own communities. Comment with solidarity; use alt-text.

This is a really good YSK. Thank you for posting!

[–] [email protected] 12 points 2 years ago (4 children)

Unrelated question, but are you a Stormlight Archive reader? I ask because of your username lol

[–] wit 9 points 2 years ago* (last edited 2 years ago)

YES! But please don't spoil. I am on the 4th book, Rythm of War, for many months now.. I have read 50% but it just goes so slowly... The first and second book, The Way of Kings and Words of Radiance, are my favorite books ever. Wit is one of my favourite characters, just so quick and witty and mysterious...

[–] [email protected] 3 points 2 years ago

I just finished rereading way of kings Friday and am reading SP3 right now! Hello fellow sanderfan

Someone called me out on this yesterday. On a thread about rblind, so deservedly so. I had no idea this is how it works though. Thanks!

[–] [email protected] 28 points 2 years ago (2 children)

That was me, and my bad. As a blind person myself, I’ve never tried to post an image. I knew including alt text was possible, but I didn’t realize the method was undocumented, and Lemmy doesn’t prompt for it. If I had, I would have offered help, not just snark.

[–] rbhfd 13 points 2 years ago

No worries! I never really considered blind people browsing apps, I only became aware of the technical details since the API changes at reddit, so it's still far from a reflex to think about.

Thanks for pointing it out though.

[–] rbhfd 2 points 2 years ago

Follow up: did I do it correctly here?

https://lemmy.world/comment/766594

[–] raiun 26 points 2 years ago (1 children)

Lemmy should do it similar to how I have seen this done on Mastodon. When you upload an image an overlay shows up to remind the user to describe the image before submitting. The typical user is not going to remember to do this.

[–] [email protected] 21 points 2 years ago

An excellent suggestion! I hope you don't mind, but I went ahead and created a feature request for this just now: lemmy-ui#1759

[–] Speckle 13 points 2 years ago (2 children)

This is really interesting and good to know, thank you for sharing. I'm going to try and remember this for all my images going forward.

For posts that are image based does the OP need to describe them or is that covered somehow already by screen readers?

[–] [email protected] 12 points 2 years ago (2 children)

Excellent question. For image-based posts, there is currently no mechanism to directly embed alt-text. This is likely to change in the future, however, so subscribe to lemmy#1086 for updates.

For now, the general advice is to use the post body to describe the linked image (on Lemmy, all posts are allowed to have "self-post"-like text). This would work by linking the image directly as usual and also embedding the same image in the post text with alt-text included there.

[–] Speckle 1 points 2 years ago

Excellent, thank you for explaining that for me

[–] Tinawebmom 1 points 2 years ago

Wait. So this is only if you post a image based comment?

[–] [email protected] 5 points 2 years ago* (last edited 2 years ago) (1 children)

There are no descriptions for image posts. You can however make a post that is both an image and text post at the same time, and throw the description there, until a proper way to put alt text gets implemented.

[–] [email protected] 2 points 2 years ago (2 children)

Any tips for a sighted person on what makes for a good and useful description?

Great YSK! Definitely doing this from now!

It doesn't play for me in jerboa

[–] [email protected] 5 points 2 years ago (2 children)

Connect and Liftoff are better than Jerboa atm, try those

[–] [email protected] 2 points 2 years ago

I'm not getting the alt text in Connect, is there an option not enabled by default or something?

[–] [email protected] 1 points 2 years ago

I tried liftoff and found it was hard to browse compared to jerboa. At least on dark mode. All the test being white and not visually distinct makes it less comfortable to browse than jerboa.

I'll have to try connect though

[–] [email protected] 4 points 2 years ago

description is accurate👍

[–] [email protected] 3 points 2 years ago

Sweet, I can actually read the alt text by long-pressing the image. This opens up a whole new avenue for good caption gags.

[–] Pillarist 2 points 2 years ago

‼️ Last time I tried it, it wouldn't work for me! Thank you!

Is there a way to embed the actual image itself and not have to rely on a third party like Imgur?

[–] [email protected] 11 points 2 years ago (1 children)

You can click the little image button when commenting or posting, but it uploads it to the instance you're on, which costs them space, so it's probably limited in most instances

[–] [email protected] 4 points 2 years ago (1 children)

And then is there a way to add alt text to that uploaded image?

[–] [email protected] 5 points 2 years ago (1 children)

Yes, when I tried it just now it uploaded the picture and put the same text into the comment that you need to link external images ![alt text](link) it just had a link for the newly uploaded photo.

[–] [email protected] 3 points 2 years ago

Thank you. I'll start doing this from now on!

[–] [email protected] 6 points 2 years ago

Thanks for this post!

[–] [email protected] 4 points 2 years ago (1 children)

Question for Jerboa users: how do you zoom in on one of these comment images? They're frequently too small to read.

[–] megahertz 2 points 2 years ago (1 children)

I'm guessing it is in settings? Also a jerboa user. But I am seeing the comment images at a reasonable size. I'm using the dark theme, and I think I changed the font size, but it's been almost a month since I first installed, so not super sure.

This is wonderful advice, it should be in all introduction material.

[–] Drunemeton 4 points 2 years ago (2 children)

Great advice! It’s pretty easy to just double paste the URL into both spots.

[–] [email protected] 11 points 2 years ago

Indeed, but just FYI: doing this is actually even worse than leaving a completely empty alt-text!

Why? Because some browsers have experimental support for AI-generated alt-text. If an image has no alt-text, it'll try to generate one, but only if the alt text is empty. This feature will probably become more common in the future, so please try to refrain from putting non-descriptive stuff in the alt-text area.

You can also copy and paste the image with Ctrl+C/Ctrl+V directly into the post or comment. Then the only think left is adding the alt text.

![Dude, sweet](https://cdn.mos.cms.futurecdn.net/f19cc921c5d2ab5c1c928088f515a330-1200-80.jpg)

that is not how to use alt text.

it should actually be a description of the image, for blind people.

also, web users who aren't using some accessibility tool can't even see it without right-clicking and inspecting the element or clicking lemmy's "view source" button (as i just did to quote your comment here). so, please don't use alt text for things other than descriptions of images!

[–] Elektrotechnik 3 points 2 years ago

Very nice, thanks for the write up!
