ALWAYS BACK UP YOUR FILES (never fun to have to re-install cuz of a stupid mistake)
- using LGP tools open and extract the file you want to edit (this one is buster.tex)
- then use biturn to convert and save the .tex file as a jpeg or any other file type you like to work with
- use your photo program to edit the pic or replace it with a new one
- using photo program decrease the color depth of your pic to 24-bit and save
- then use Image2tex to convert your new pic to a .tex file and rename it to name of the file your replacing (buster.tex)
- using LGP tools right click on the file you want to replace and click replace and point it to your new .tex file
if done correctly your new pic should be in game, i know when i first came to this site and started modding in May it was so confusing to me but the more you play with it the more you start to understand...Good Luck dude
