how do i get my pictures looking like the ones u get from the machines(like a lil photo booth)? will i need photoshop or paintshop pro? if so how can i get those? like this:

You could probably do that with plain ol' MS Paint. All you have to do is take a few images, make them the same size, then line them up.

ummm...how to make them the same size

When you paste images, there are little squares in the corners and sides. Click them and move them around under the image is the size you want it.

If you really wanted to (on MS PAINT) you could open up four images separately (the ones you want to use of course) and go to Image then Attributes. You can adjust their sizes individually that way. Then open up a new one and copy and paste them so that they are the way you want them.
