I don't think Imagestation allows remote linking. There are several that are free that do allow it. there are some that you can pay a small fee for larger storage and bandwidth. If your internet provider has free webspace or a free webpage builder then you can put them there then just link to the web address of each photo. I know Verizon online has it, and I'm sure many others do also.
I use villagephotos. I don't know how they compare, as I didn't really do much research on it, but I have alot of bandwidth for a pretty nominal charge. They have a limited free service. I would bet there are free ones out there that have more bandwidth though, maybe someone could list one or some for both of us..
Saurian, you must do some digging to bring all these old threads out of the closet!
