Create a new image and depending on if you want them vertical or horizontal, times your width or length of your new image by whatever you 6 images total, You don't mention which version of Paint shop pro, so I'm using version 5 (yeah I know, old
lol) in these screen grabs.
example: - I have 6 images are 300x225 each and want them vertical in a rectangular box..
1. Create a new image 300 wide by 1350 length.
2. Then highlight the picture you want to go in the rectangle (I'm using the red clio as an example)
'Tools>Selections>select all' bar at the top..
You should get a full area grab of your picture..
If you look at the clio picture, it's got the dotted lines round it, Now select Tools>Edit>Copy..
3. Then you'll need to transfer it to the new created image (white backdrop in the middle)
Click the new image, then
Tools>Edit>Paste>As New Selection..
4. Soon as you click that, it should transfer over the clio image into the new image as a selective image .. Like this..
you should be able to move this about freely and decide where you want it placed..
then each in turn, repeat the procedure with each of your images... You should end up with something like this...
