It is indeed outside the terms of free hosting. There is a 1gb limit on image galleries, and the account cannot be used for file hosting.
That said, whoever suspended you made it clear it's a warning, so I can give you 24hr to bring your account in line with the TOS. I can also tell you that you're about 6.4gb over the limit on image galleries, and you'd have to actually install a gallery script of some kind as this isn't currently an image gallery.
I can unsuspend this as soon as you agree to bring it in line with the terms within 24hr.
