I think Terry will have to clarify that.
I noticed that images posted here are displayed full size when you click on them.
If you intend to sell the photo as stock I would upload it only to Kachoozie.com where they are limited on display size.
You don't want the public being able to copy your full sized images if your intent is to sell them.
I'm not 100% certain but I think Kachoozie.net is mainly for socializing and sharing images that you may not have intentions of selling.
Hey folks, Steve is correct, on the .net site you should upload images you want to display, if you upload on .net the images should be smaller, and I generally have my watermark on mine. For .com , those are autowatermarked and should be full size.
