Although Paintshop Pro can do a lot of things, sometimes, other programs can do a few things better, or things that PSP cannot do.
This is the case of Wordle, a little online program that will allow you to create some word clouds. Word clouds are a bunch of words displayed somewhat at random, but with the size based on the weigh of each word. The weight is normally based on the number of times a specific word will appear in a list or a text.
Wordle is a fun program to use, but it only offers the option to print or save as a jpg (meaning it will have a background). If you would like to use the Wordle features, but would prefer to add the text to other backgrounds, you can do that with Paintshop Pro (and probably most graphic programs too).
