I am sorry to hear you weren't able to register on the forum. That is weird, I haven't heard of any other problems. The only thing I can think is that you might have had trouble with the confirmation code. I know I have had issues with those things. If you are willing, give it another try. If you are still having troubles, sent me your email and I will get your info entered in and shoot you an email back.

Uploading images is very easy (assuming you are using the appropriate file types). Once logged in, there is an Upload file link on the sidebar which you can click to get the file on the site and available to use.
