I second the motion using AJAXplorer. It works perfectly at my church for the photographers. They upoad different images and such for different events. Furthermore, you can edit with ease, who has access to which ibays or webshare.
I don't know of a way to convert an IBay that is already in use to a webshare available for AJAXplorer. I had to delete each of my ibays and start them over using webshare and not IBay Creation. Maybe someone has a suggestion on that, but AJAXplorer is definitely the way to go
