Welcome to SimV, ATC7.
It's not difficult to download additional textures for a plane; there are lots out there. There are just a few simple rules:
1. you need repaints for the specific plane model you have; e.g. if you have the Meljet 777, then only repaints that specify this plane will work with it. This is because the texture mapping is part of the original model in the 'model' folder.
2. follow the instructions with the download. This will normally give instructions for the naming convention of the additional 'texture' folder(s), and the changes you need to make to the aircraft.cfg file for the new texture to be recognised.
Post again if you need any more help.
