GIF artwork "Please choose a branding image" HELP

[PlusPlus]

I made a gif and I wanted to upload it, but it says that I need to choose branding image.
What is it? How do I do that?

First queston: Is the GIF actually an artwork or have you simply tried to post a video in the wrong section?

Its a .gif not a video

[ReBoot]

Tell that to the countless people who simply record short clips and upload them as GIFs.

Ok, now we know its a actual gif. Can you help me? After several tries It doesnt even ask me for branding image anymore. It just jumps to the top of "posting page" if I may call it that way. Then nothing happens.

Ok, there must be different problem because I cant upload anything at the moment...

it asked me for it on artworks, I dont know whats wrong with steam...

The "You must choose a branding image" error usually appears because you haven't even uploaded the artwork yet. If you get the error, it's probably because you've tried to upload without ever clicking "browse" and selecting something in the first place.

No, I did choose it. But thanks, that might mean that problem is on Steams side. And as I said, It doesnt show that message anymore. Its just loading and I get black screen in Steam app.
