Not difficult to use - create a new Directory, and tell it if you want it to be public or private... Then upload pics. Not too big mind.... the size they are uploaded is the size they appear, so stick a 2000x2000 image on and it'll be too big physically, however it seems to work ok with the testing ive done.
tried a pic direct from the camera and it got to 100% uploaded but then just hung. I've just been told that the camera is 12meg. It was easy enough to resize on PS though
