In Phrogram we look into the mesh file to see what the related support files are and load them for you, the image viewer don't show the .X files but if you go to the directory you will see them.
Right click on the image folder in the files view and click open folder, you can grag and drop, cut and paste into this folder any images you like.
On the 'Downloads' you will see that we have posted a lot of other free 3D stuff in the 'free images and sound' section check them out.
there are a few types of .X file formats out there and some don't work with Phrogram at this point, so we are going to post more contect that we know works with Phrogram soon.
