Here's something simple and fun to play with.

Breath Life into Me Tut.
1 Open an Image in PSP
2 Use your Freehand Selection Tool to select the area that you want to add movement to. I set mine with Feather at 3.

3 Go to Layers Duplicate.
4 Repeat step 3, so that you have 3 Layers.
5 Click on your first layer to Select it.
6 Go to Effects - Distortion Effects - Pinch - Put your Strength % to 6 Click OK

7 Go to your top layer - Copy (2) of Raster 1 and Select it
[We have purposely missed the middle Layer]
8 Go to Effects - Distortion Effects - Pinch - Put your Strength % to 8 Click OK
9 Go to File and Save as PSP Animation Shop.psp
10 Open Animation Shop and Browse to your Saved Image and open it.
11 Go to Edit - Select All
12 Go to Animation - Frame Properties and set to 50.
13 Go to File and Save As and save as a .gif File.
14 To View your Animation, Click on View click Animation
You can have a lot of fun with the Pinch Effect.
Gosh, you can have a lot of fun with PSP.
Happy PSP'ing
