I am getting this annoying error as I am trying to upload screenshots of my app before submission.

• The error appears after I upload images for any screen size, and when I try to upload more images for another size.
• It appears in the Version Information screen but also in the media manager.
• It does not matter how long I wait between uploads and does the same with Safari and Firefox.

Has anyone of you seen this and found a workaround?

Thanks

For me saving the images as jpg (instead of png) resolved the problem.
