If you want to have different images for each forum that you have created inside your vbulletin board as you can see in this two picture:
Before (pay attention: there are some category with opacity 0.5: this are the category with old threads)
After (firefox icon is changed)
For doing this you have to install before this Add-on: Forum Icons (I put as attachment the product that you need)
BUT
1. Install only the product
2. Go Into Admincp --> Forum and Moderators; Modify each forum putting the path of each image where it says "Add the path to the icon image here."
3. Go Into Admincp --> Styles and Templates --> Manage Templates;
Edit forumhome_forumbit_level2_post
