Editing, converting, and saving

First things first, find or create your own image. In this example, I will be using the Dire wallpaper created by Perfect World when they announced that they would be publishing Dota 2 in China, available. Any image will work, but I recommend that the picture's resolution is at least what you plan on running Dota 2 at. I run my game at 1600x900 resolution, so using this picture will not produce any unwanted stretching or pixelation.First things first, open the image up in your choice of image editor. Then, make any edits of your choosing.Then, save it as a .TGA file somewhere where you'll be sure to find it later.If it asks you what resolution you'd like to save it at, just choose the default or 24 bits/pixel with no compression.After you've saved it, open up VTFEdit, and under File, choose Import. You can also press Ctrl+I (as in Imogen) to bring up the same menu. There, choose the .TGA file you just created.Then, you may be faced with a daunting window asking you for things you don't understand. If you don't know what any of it means, just copy the settings I used:VTFEdit will then load in the picture as a .VTF file. No editing will need to be done here, all you need to do is to go to File and then choose Save As... and save the .VTF file somewhere you'll be able to find it.
