Description

Graphic Image Map ? (GIM) is an image format, allows for tenths of different storage settings and by combining settings results in hundreds (or thousands) of different GIM files that are structurally different, to simplify concepts people is naming this different GIM files as "GIM formats" but strictly speaking the GIM format is always the same, the amount of GIM formats used in PlayStation consoles is limited though (restricted by the graphic enviroment, libraries, etc...). GIM files was found used in PSP and PS3 firmwares inside Resource Container (RCO) files, PlayStation 3 Theme (P3T) files, etc... See GimConv and Multimedia Formats and Tools#GIM

The acronym of GIM used in this wiki (Graphic Image Map) is an speculative unnofficial name based in how the data is stored in the internal GIM structure, if someone finds the official codename somewhere please report back and we will change it
