Super easy. Do you have MS Office? I use Powerpoint, myself, inserting them and just lining them up.
This.
Or almost, anyway. The process I use in PP goes something like this:
1. New document. Resize it to A4 (because for some reason PP defaults to on-screen slideshow, and I haven't been able to change that default).
2. Insert a square in the document.
3. Resize the square to 25 x 25 mm (for a Medium critter) and change the border to 3 pt or something like that.
4. Change the square's fill style to "image" and select the right one - usually from CCD, but sometimes I use pictures from other sources I have prepared ahead of time in IrfanView (by proper cropping).
5 (optional). Add a number to the square, and fiddle with it so it's in a reasonable size (14-ish points) and in one of the square's corners.
6. Copy-paste the square as many times as needed and repeat relevant parts of the process. It takes less work to copy-paste a square and then change the picture than it takes to make new squares for new critters from scratch.
Oh, and I have PP set to "snap to object" rather than "snap to grid". That way I can fix the squares so they fit snugly on the sheet I print, which means less work when cutting them out.
