EDITING GTA BY USING MODS

First of all the "gta3.img" files is the one that haves most part of the game models, textures, collision files, some path nodes and some animation files.
Things you can install in SA with the "gta3.img" file:

• Car mods.
• Weapon mods.
• Player mods.
• Map mods.
• Any texture mod.

There also others files with the ".img" extension, like "player.img" that has all the player clothes and vestments you can buy in the game, including the hair styles also.
What do you need to install mods in the IMG's?

• An IMG editing tool.

Note that not all released IMG editing tools work with every GTA. It is recommended you find the very latest release of a program in order for it to work with the latest games. Always read the readme.
Some common IMG editing programs are:

• IMG Tool
• ImgEd
• Spark

You can find them in the Tools section of GTAGarage (Gtagarage.com).
Now that you downloaded the IMG Tool you can open it, the first thing you will see is this:

Check this image:

You have to click "Commands" then "Add" and now you have to search in your computer the files you want to ADD to your gta3.img. In my example case the "Leon.dff" and then the "Leon.txd" . Alway add or replace 1 file at at time.

Now when you have to Replace an existent file you first have to search it in the gta3.img, to do this you have to go to "Edit" then "Search", type the name of the file you have to put as a replace in the gta3.img. For example: you have to replace the "ballas1.txd" file because in my mod is a Zombie Texture included in the Fix Patch, you type that "ballas1.txd" in the search and the IMG Tool will search it. Now you are ready to replace:
