Trying to upload some banners made with createjs in a website and I get this error in Firebug:

This is due to the same origin policy, if you do some research you'll be able to come up with a suitable solution for your use case.

Sorry, I don't understand what you mean. If I'm asking is because I don't have any idea why it's happening. Could you please be more specific? thanks (I'm not programmer or anything like that)
