I use a program called Irfanview to view all my photo's and videos.
You will easily find it with Google, and the price is right.....
Yes, it is free.
You can easily do lots of things with it......
ie, change a pic from colour to black and white. Adjust colours..... Ok this is a bit tricky but can be fun to experiment
Also easy to change the size of pic......
Get it up on the screen, zoom out, press File, then Save as.......
A box will come up, one of it's options is File Size, I adjust this to 96Kb,
gives adequate pics on here and elsewhere.
Then do what Robb said to display it, sounds like a lot of messing around but is actually quite easy. Hey ! if I can do it.......
Photoshop I do not understand at all.......
