This script is made to allow hotlinking images from other servers where hotlinkin has been tried to set disabled. With this you'll never see image not loading or getting "This image is hosted by tripod" like images instead of the one you're trying to use on your webpage.
Example that I used to test is here:
Try to use that url in IMG-tag on your page and it will not load. However using this script can show it. Just use it like this and it will load the image on your page:
As you can see, the script take 'src' parameter for path to image you want. You can also resize the image to smaller by prowiding x-parameter for width or y for height. Use only one of them and it will calculate the right value for the second one so the images proportions will stay right.
For example to resize that 550x347 to half, use url like this:
By default the script will return a PNG image, but by adding 't' parameter you can ask it to return gif, jpg or png. Values accepted are 1 (GIF), 2 (JPG) and 3 (PNG).
Enjoy!
