Randomizer works by receiving a request to pick an image from a particular directory. This request is sent from an image tag. Instead of pointing to a specific image, the image source is the Randomizer script.
All you need to do in order to use Randomizer is build your image tags with calls to Randomizer. There is no maintenance necessary.
There are a few key pieces of information to include in the tag and these are:
- The call to randomizer. You call Randomizer by making the image source the relative location of Randomizer.
- The location (relative to the servers root) of the directory to pick images from. This is preceded with 'dir='
- Type of image. You should specify either GIF or JPG This is preceded with 'type='
So an example of an image tag which would call Randomizer would be:
<img src="/cgi-bin/random_image.cgi?
dir=/www/htdocs/images&type=GIF">
/cgi-bin/random_image.cgi being the location of Randomizer.
? denotes the end of a url and the beginning of augmented information being sent to the url.
dir=/www/htdocs/images is the location of the directory which contains the images to choose from.
& denotes that there is more, but separate, information being passed.
type=GIF is the type of image to use.
