Mindjongg tileset
Mindjongg (also written MindJongg) is a Mahjong Solitaire video game, developed by Minder Technology. It is for 32-bit Windows, 1998-2006 era.
The later versions of Mindjongg have a native .IPG format for tile set graphics, and may include an editor. It's undetermined whether IPG was introduced in version 6, or version 5.
Mindjongg was originally named Shanghai 97. The versions that use IPG format are all named Mindjongg.

Disambiguation
Minder Technology released a different Mahjong product named MJ (Network Mahjong). So, one should avoid abbreviating Mindjongg as "MJ". MJ does not appear to use IPG format. Some Mindjongg distribution filenames start with "mg" (not "mj").
Format details
An IPG file contains embedded image files in standard formats. Possible formats include BMP, GIF, JPEG, and TGA.
