I have a problem while saving, after a long time 'sending the image', an error message appears, that says 'error conecting the server' or something like that... can someone help me?

Okay, It has already been and hour and I can't send my revision yet... what's going on? it says: "IO Error: Error wrtriting to server".

what program are you using?

Lascaux.

can you open the java console and see if there are any errors displayed there?
I would suggest taking a screenshot, then trying to refresh the page to see if you can restore the image and resubmit it. if not, I can restore it from the screenshot (but you'll lose layers, etc.)

Ok, I'll try. Thanks Cello!
