Ok,
1st - if yr using Dosbox, you can press ctrl+f4 to take a screenshot.
If you're not using dosbox, you can use other software. I use FRAPS for most games and short videos and Snag-it occasionally.
You can find and download either by googling their names, like "FRAPS download PC".
If yr running the games in a windows dos window, then print-screen should work and is probably easiest, unless picturetheif does it. I've never used that one before.
What's non-dosxbox?
There are loads of ways to re-size an image in windows.
When you right click on an image file (jpg or something) and click edit - what programme opens up..?

btw - the stuff I said about posting a load of screenshots at massive size was a joke because your signiture was SO BIG!!!

If you had posted the screenshots *and* had a humungous signiture, it would've been an ultra-long post!
That idea of that made me LOL
