Hi. I found a great script for stopping hotlinkers. The only things that I need to know are:

1. Are these scripts case sensitive? (.gif vs .GIF)

2. Do I need to write the different extensions separately? (gif, GIF)

3. Can I write the different types I want blocked together? (.jpg .gif .mpg) etc... or at least the different variations if I need to write them separately? (jpeg jpg JPEG JPG) and so on.

Thanks bunches
