If the pictures are larger than the maximum allowed, yes ....open the picture in paint, click file/save as (rename it perhaps the same name and add the word " resized" if you want to keep the original sized picture also. Then click the stretch/skew and i usually tell it 50/50 on the %, which should make it small enough. There are various other ways to resize pictures, but sounds like you have a pretty good handle on the process through paint. Good Luck, post again if you need more help.
