This thread will explain how you can get a custom background in CS:S for both 4:3 and 16:9 aspect ratios. A program is needed. VTFEdit: http://nemesis.thewavelength.net/index.php?c=238 There are two categories. 16:9 and 4:3. Find your aspect ratio. Spoiler: If you use any of these resolutions you have 16:9 Spoiler: If you use any of these resolutions you have 4:3 Tips. Don't pick an image with a white background. It will make the menu hard to see. Spoiler: Background examples 16:9 Aspect ratio. Filename: background01_widescreen from topbadge hud 4:3 Aspect ratio Filename: background01 from windows xp Tutorial: Open VTFEdit. Press the Import button or press file and then import. Find the picture you want to have. Select it and open it. A "VTF Option" window will pop up. Copy the settings for your aspect ratio. Spoiler: 16:9 Settings Spoiler: 4:3 Settings Press Save As... and save the file to either "background01" for 4:3 or "background01_widescreen" for 16:9. Put the VTF file into: C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Source\cstrike\materials\console. Create a "console" folder if there is none. If you are using any type of custom hud, e.g TopHud. You need to install it inside your hud folder. C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Source\cstrike\custom\"Whatever hud you have"\materials\console IMPORTANT STEP! Delete any VMT FILE. NOT VTF, BUT VMT! It will be a text file with some rubbish coding. It will prevent your background from loading. It will appear at the same location as where you saved the VTF file. Open CS:S and enjoy your new sexy custom background! I hope it helps! If you have any issues or need help. Don't hesitate to ask below. Some HeLL backgrounds for you to enjoy.
