Fuzzy... Ma man. We're gonna need something better than 'some server side error occurred' to debug your issue. When you see the error again, do me a favor and copy the text it gives you fire off an email to me.

....while ya in the mood...we've had a few of these in the last day or two.....maybe down to spanner-wielders fiddling during the uploads...

i will look into this and get back to you

Hmmm, the plot thickens. It's only certain photos which won't upload, though they are all jpg. The error is...

Server Error in '/' Application.
