I manage a number of sites and I have lots of images that I use. I have, until now, stored these photos in my computer on my hard disk and uploaded them to the various sites when required. Now I am creating of online stores on Etsy and eBay and I think it would be simpler to store the photos on a site that would assign a URL, so the image could be reused on a number of different sites.
Here is what I have done so far, I have three possibilities that I am experimenting with: Picasa, Flickr and Box.net. Each assigns a URL so that I can reuse the asset. Who has experience doing this? Are there other suggestions for sites that have greater flexibility???
