I use Google's Picasa for editing my photos for this blog. It's free to use and really helps with improving the photos I've taken with my digital camera. They also have a 'Web Album' you can use to store your photos online in private or public albums.
I've gone through the grief of having a hard drive crash and losing lots of photos that weren't backed up or saved onto CDs/discs. So do yourself a favor and try Picasa, or others like Photobucket, Flickr, or Xanga for storing photos online, all free to use and access wherever you can get online.
