I have a question along similiar lines, hope no one minds me asking it here.
I am looking for a software package that will allow me to store both .jpgs and .gifs on my site. I will need 100x100 thumbs as well as the full size pics up to around 400x400 on occasion. It will need an interface that makes things simple. I use Earthlink as an ISP and they used to have a great little image storage feature free for us until they shipped everything off shore and spoiled it all. Something like that would work.
I am prepared to pay for this but free is great, heh heh. It would need a password feature, and some way I can protect my images. Sounds like I'm asking a lot but I'm sure there is something out there. I've been Googling all afternoon and came up empty.
