Issues with getting content from Pixiv

Today I tried fetching some art from Pixiv, but it didn’t work despite it’s written that it should, so I had to save it to my PC and upload it from there.

I also found an animation I thought I’d repost, but Pixiv doesn’t provide any means to download animations. When I try to save it via right mouse click like I do with static images, it just… becomes static. I found some Chrome extension (I normally use Firefox), which allows to save GIFs and WEBMs, and it works, but I ran into another problem. While in Firefox the animation looks fine, in Chrome it’s too dark, and it remains like this even when I save it to my PC. I looked through the artist’s gallery and it was the only animation affected by this glitch.

I checked the Contact page, but I would rather not use either option there for personal reasons.

Yeah, I noticed the Pixiv thing too, though I chose not to bother Pup, as they seem to be quite busy otherwise. I think the animation thing is because animations on Pixiv are literally not animation files, but instead separate images for each frame with a JavaScript cycling them.

A useful trick is to copy the image (not save, literally right-click → copy image), because you can then paste it directly into https://saucenao.com/ and use it to check whether the image has been uploaded to e621/rule34, and then possibly upload from there instead.

Thank you, I found it on E621 and fetched from there.

Fetching from DeviantArt doesn’t work either.
