Hi, chriii. Welcome to Sysnative.
Shutterfly advertises that unlimited photo storage is free.
Photobucket supports the following file types:
Supported File Types for Photos and Videos : Photobucket Support but free storage is limited to 2GB.
Free Microsoft SkyDrive is limited to 7 GB:
SkyDrive - Microsoft Windows
I don't know the limits for
ImageShack® - Online Photo and Video Hosting other than each image must not be larger than 1MB in size.
Imagebam is limited to JPG, GIF and PNG images and each file must be 4MB or smaller.
Bottom line, with 30+ GB of pictures and home movies, you could split the files among various free sites but you never know when any of those services will be discontinued. Particularly, if the photos and moves are not replaceable, I would recommend backing up to CD/DVDs or, probably a more practical solution as well as easier to use, a portable drive such as a Seagate Portable Drive.
