Today I got this error in Windows Live Writer when I tried to publish a post that included an animated GIF file.
"Can't publish files" "The remote server returned an error: (500) Internal Server Error."
When I tried to upload the GIF directly to Picasa Web Albums using Chrome the progress just hanged like this.
Or the Server rejected error as seen in Internet Explorer.
Anyone else seen this issue? Hopefully I'm not alone and that Google fixes this bug ASAP.
UPDATE: The problem has been fixed.
