//Creates an image catalog from the graphic files in a selected folder. 
//Each file can be labeled with the file name, and the labels are placed on 
//a separate layer and formatted using a paragraph style ("label") you can 
//modify to change the appearance of the labels.

//The myExtensions array contains the extensions of the graphic file types you want 
//to include in the catalog. You can remove extensions from or add extensions to this list. 
//myExtensions is a global. Mac OS users should also look at the file types in the myFileFilter function.
