Just a quick note, at a users request I have done a mod for this script that allows you to get a random image to use on other websites to promote you ModelIndex website.
After having your copy updated (or with fresh installs) linking to the following image:
http://yourdomain.com/random-model.jpg
Will generate a random image of one of the models you have added to yoru site with their name. You can then use this image as you would any image and link it as you see fit.
As an example here is the one for the test site:
The above image will change everytime you visit this page ;)
If you need it installing hit me up, if you need a copy of the script . . . err still hit me up.
Good Times!!!
