I trying to upload banner and screenshot with .gif and .png, but the image is not load correctly

I am trying to open the image, and i got message "The image [img path] cannot be displayed because it contain errors"

We had some downtime with our image processing server. It should be restored now. Tell me if you are still having issues.

It is not necessary to re-upload any images, as uploads are handled separately.

I think the image isn't error, this is my screenshot page: https://imgur.com/a/eD0hCRv (I use Imgur because i can't upload images here too)

I've just had a problem uploading a newly revised banner image. It's possible it's a problem with the zone website (where the images are hosted).
