Most screenshots are stored in BMP-format, which takes a lot of HD-space. With XnView (free download on>> http://www.xnview.com/ you can easily convert hundreds of them to JPG. Even if you set the JPG quality to 100% the JPG-file can be less than 15% of the BMP-file. 100% is good enough to print, if you took the shots from a full screen. Normaly I use 80% (filesize less than 5% of BMP), it's good enough for normal prints. If you use the shots only on the screen you even can go to 60% which gives you files that are about 3% of the BMP files.

XnView offers a lot more. It can import 400 different file formats and export 50 different file formats. You can normalize, crop, scale, rotate, stretch, import from clipboard, and much, much more (more than you'll ever use).
It's available for Windows (in 44 languages), Linux, Solaris, MacOS, and more.
The best of it: IT'S FREE!

Yeah !

In France, the net surfers use usually ACDSee, or program of final improvment (? sorry for my poor english, it's google translation for program like photoshop, the gimp...) or IrfanView (good program)
But that given pleasure of seeing an Xnview user : why ? It's a french free program !!
