For those who are using PSP 10 and up, here are some instructions on
how to add Animation Shop to your PSP workspace so you can launch it from
here instead of having to go to your desktop or start menu programs to do so
  This is made possible by a free script created by Suz Shook  which I have
attached:
 
NOTE:  You must make sure that PSP is closed before saving the script to
your Scripts Trusted folder and then once that is done you can Open PSP and
start customizing.
 
First save the attached script to your Scripts-Trusted folder then: (see
diagrams below)
 
1.  Click on a blank area of the workspace.
 
2.  Click customize from the drop-down button.
 
3.  Click on the Scripts tab.
 
4.  Find the script 'ss-Start Animation Shop' in the drop-down list.
 
5.  Pick an icon to associate the Animation Shop with (any one you like).
 
6.  Click on bind.
 
7.  Drag the 'ss-Start Animation Shop'  to anywhere on your toolbar you
would like it to be and then click Close.
 
That's it!
