This is as far from guitar or music as possible.  But  @Clayton 's recent discussion about uploading photos reminded me about this little graphics viewer that I use. 

I don't think it's an exaggeration to say that I use it every day. If I don't, it's close.  It is called Irfanview.  And it is more than just a viewer.  It is a viewer, print utility, file converter, editor and I'm sure it does other functions I don't know about.  And every step of its use is intuitive and simple.   It will even build slideshows or screen capture.  If one wants to convert a file type it doesn't require going through a conversion process, just save it with a new file type extension.  And printing it will resize according to paper size if you want to make a full page or you can resize and put it anywher eon the page.

And, most importantly, it's free.  And it's not free in the sense there is a time limit or donation expected.  Mr. Irfan Skiljan released it to the public domain with no restrictions.

Just a great little utility and I've been using it for years.  Of course, I use Photoshop for important complex photo manipulation and anything needing layers.  But for quick image viewing or printing I use Irfanview, as I said, almost daily.
