I used to use Yahoo! for my photos, but I was very disappointed when the ‘free’ service cut some of the options that I found very useful for photo management:

FTP upload (for lots of photos)
see full size photos,
security of images

*Yahoo also removed access to the original images online, which maddened me, but must have p****d off a lot of people.
*removed ftp access
*removed online access to viewing the original size images, too.

Since I now have my own website and hosting (not through Yahoo!), I’ve been much happier. I can control a lot of aspects, true. It is more trouble, since I have to think about the set up more, but then I can avoid all the other issues above!

I would submit that other photo websites also could circumscribe users in similar ways that you might find annoying, esp. if you don’t keep the original fotos somewhere else.

my 2c worth.
