As you go down the Irfan-HyperSnap/MWSnap/etc. path you might take a
look at FastStone Image Viewer (free).  Combines image view and
capture of these programs and then some in one program.

Compressing jpg files is not very effective (jpg is already very
compact).
(same applies to .pdf files)
 
As an example: taking a photo whose jpg file size is 16.9kB and using
highest
compression possible with WinRar results in a file sized 16.8kB. (more
compact
than WinZip can do). Same photo saved as .png file has a size of
110kB!
 
On the other hand, for screen shots (having limited number of colors
normally) 
the story reverses: a .png file has the size of 4.33kB while the same
file in .jpg format is 21.2kB.
 
So, choosing file format in which to save graphics files is more
important than external compression
engines. Sometime, you will have to experiment to find out.
 
HyperSnap screen saver has some editing features lets you save
information in various formats 
but is not free. 
 
IrfanView is a viewer with some graphics processing abilities
(http://www.irfanview.com/) <http://www.irfanview.com/) >   
lets you save files in different formats and is free.
