Usage:

1. Go into your installation of PhotoShop's files and make backups of IconResources.idx, PSIconsHighRes.dat, and PSIconsLowRes.dat

2. Unpack data using the following command:

python3 psirm.py unpack /path/to/folder/with/IconResources.idx /unpack/base/path

PSIRM will create High and Low folders in /unpack/base/path if they do not already exist and dump images from PSIconsHighRes.dat and PSIconsLowRes.dat in their respective folders. Note: Folder file contents will not be identical, some images exist as only high resolution or as only low resolution.

4. Modify images as you wish as long as they are no larger in file size then the original. This is due to a limitation with the program, as it does not know how to change the icon header files properly

5. Re-pack images back into resource files with the following command:

python3 psirm.py pack /path/to/folder/with/original/IconResources.idx /unpack/base/path

PSIRM will use the High and Low folders in /unpack/base/path to create modified resource files in a new folder in /path/to/folder/with/original/IconResources.idx named modified. The program still needs to read data from the original version of IconResources.idx, but will use that information to make a new version in modified/IconResources.idx, as well as new versions of PSIconsHighRes.dat and PSIconsLowRes.dat.

Disclaimers:

This program is not supported by Adobe and is not affiliated with them in any way. If you don't make backups of these files and skrew up your installation of PhotoShop using this program then it's not my problem or Adobe's. If you encounter any issues other than the fact you can't make replacement images be larger in file size than the original, please make a new issue describing what is going wrong.
