Using 4images

[pkitty]

I have a site that has a zen cart....a shopping cart installed on it.....my question is this...the gallery of 4images, will be used mainly attached to the forum, to display artwork...not used in any other way...locked down and for members only....do I need a license for that??? I hope not, but I just want to be sure, cuz if so, I will have to find another gallery....needing a license would be to use the gallery to sell goods from right?
