Only PNG images work? Can't use JPEG or WEBP images.

[onetrev]

I didn't see anything in the docs about this, but every time I try to use a JPEG image, I get the following response:

400 {"type":"error","error":{"type":"invalid_request_error","message":"messages.0.content.1.image.source.base64.data: The image specified was not valid"}}

If I then try to use a WEBP version of the image instead, I get:

The file is not an image.

The only thing that works for me is instead saving my image as a PNG.
