Hi Colin_S,

Poser 4 used the .rsr file for the thumbnail image in the Library.

Pro Pack started using .png files for thumbnail images.

You don't really need either one because ...

If the thumbnail image i.e., .rsr or .png, is missing, you will see the little shrugging guy in the Library.

How to make a new thumbnail image.

1. Load the item from the Library
2. Adjust the image in the Document Window (use a square window, e.g., 256x256)
3. Save the item back to the Library and ...

Poser will create a new thumbnail image for the Library.
