How to rebuild a PS3 RCO with custom GIM images using Rcomage and GimConv

1. - Extract RCO. Use Rcomage to extract the RCO contents without image conversions (so GIM files are extracted as GIM) to a folder named RebuildMe. This files are going to be used to find the original GIM setting and for RCO rebuilding purposes
2. - GIM to PNG. Identify visually the image you want to customize by converting it to PNG. For this example the image is named icon.png. The conversion to PNG can be made by two optional ways:
   1. - Use Rcomage to extract the RCO contents with image conversions (so GIM files are extracted and converted to PNG) to a folder named DontRebuildMe. This files cant be used for RCO rebuilding purposes
   2. - Or use GimConv to convert the original icon.gim from RebuildMe folder to icon.png
3. - Custom PNG. Use icon.png as the base (mostly to respect the original width and height) to customize it in any image edition program (gimp, photoshop, etc...)
4. - Find original GIM settings. Use GimConv to find the original GIM settings of icon.gim from RebuildMe folder by making GIM-to-GIM conversions
5. - PNG to GIM. Use GimConv to convert the custom icon.png to icon.gim with the GIM settings found in step 4
6. - Overwrite original GIM. Copy the custom icon.gim to RebuildMe folder overwriting the original icon.gim (this is the only file modifyed in RebuildMe folder along all this explain)
7. - Build RCO. Use Rcomage to compile the RCO with the files from RebuildMe folder
