Error message when trying to post an image:
Slightly different error on mlmym interface:
Funnily enough, I seem to be able to upload these small screenshots embedded in a post just fine. The photo I'm trying to upload is less than 2 MB. Is that too large?
Any relation to these problems?
Any other info which might help diagnose the problem?
A1: probably, although that's more processing power. The tool I used to fix it would have outputted a second image file if the extra data had been an image, which is then a weird case to handle. (Upload both? Make 2 links?) Certainly, it could output a better error message though.
A2: Should be lemmy-wide, although technically a malicious server could disable that somehow, which I think would only affect their local users. ie: don't make an account on a server you don't trust.
A3: It is a server specific setting. It's easy enough to change the setting. Bigger limits uses more storage which costs money
A4: Possible, I would think. No idea if that's ever on the devs' roadmap. I think that would be added to the pict-rs code which is then used by the lemmy server.
Both are open source projects, so an instance implementing this could then share the code so it's eventually a feature for everyone.
I've ran into bugs before on some public image host I don't remember where it wouldn't strip metadata if you uploaded an album. It's probably a good practice to strip metadata before uploading, although much less convenient. I double-check that it still works here from time to time, doubly so after upgrading versions.
Thanks for your detailed answers!
I came across these discussion threads in the Lemmy and Pict-rs source code:
Is it possible that automatic compression has already been implemented? Might it just be a matter of passing an additional argument to pict-rs?
