UpdateBanner: gifs don't work

[Datamine]

I just ran into an issue with Api.UpdateBanner: I noticed that I could use the function to upload .jpg files seamlessly, but when I tried to upload .gif images, I got the following error:

twitter.error.TwitterError: {'message': 'Image data could not be processed'}

I'm wondering why this is the case. I tried it for two separate .gifs. On twitter, I can upload those files manually without a problem. I looked into b64encode, and also couldn't detect any issues there.

Here is a gif for reference: sample

Update: converting any problematic gif to .jpg using ImageMagic allows you to upload the converted jpg.

I don't think that GIFs are supported on that endpoint, but the web client may be taking your GIF and converting it to JPEG/PNG. I'd try asking at https://twittercommunity.com, since that will probably be a better resource than trying to figure out what the remote server is doing.

@jeremylow good call. I've opened a thread there: https://twittercommunity.com/t/update-profile-banner-doesnt-work-with-gifs/83288
