I find it easier to join the pics together in another editing package (like
GIMP or
Irfanview. You can use GIMP to add speech bubbles etc or you can use photobucket to do it (upload the pic, click 'edit', choose 'decorate' and there are speech and thought bubbles there).
If you decide to download GIMP there are lots of instructions for it on
wikihow.
Hope that helps!
ETA: I can join the pics together quickly if you want to email them...
