There are a number of ways you can reduce the size of them and programs etc, I use paint.
Go to where you have saved your photo's, choose one and right click on it, a drop down menu will show, pick "open with" and another menu will show, choose "paint" and when that comes up click on resize up on the left, backspace on 100 and put in 25 (or can use a bit bigger if you wish) and then go up to the little save screen that looks like a TV and click on that (the save button). Carry on with other photos etc.. Hope that helps...
