I created 2 Photoshop actions which will take a square .tif file of any size and convert it to a 91x91 pixel picture that will save properly as a .png file for Poser to use. One action makes .png files with a blank background, the other makes .png files with a white background. I know the actions work in Photoshop 7, but I don't know if they work in earlier versions. (I don't see why they wouldn't ....)

If you use P4, you'll need to convert the thumbnails to .rsr files using a program like P3D0 Explorer before you can use them.

The actions are in the FreeStuff under 2D. I'm mentioning them here in case people only check Poser freebies.

Hope you guys find them useful!
