This hack will randomly change the forum logo for users randomly every (images/1000) times.
If you have five images then there is a 5 in 1000 or 1 in 200 chance the user will see a “changed” logo.
It usually freaks people out and is a lot of fun.
Works on vBulletin 3.6 and above.
You will need to edit the image url’s as you need. For examples I added in 3 images named logo_random1.jpg through logo_random3.jpg
