Random Image Grabber


Refresh this page and this image will change to a random pick of nine images.

The first thing you need to do is rename all of your files of the same file type to be a file prefix (optional) followed by a incrementing number. Then, upload them to a directory online the preserves the file name (Photobucket, FileDen, etc.) Finally, use the following code to fetch the random image script which will return the URL of a random image.

The Code
<img src="http://krisallen.net/extras/randimggrab/randomimagegrabber.php?dir=YOUR_DIRECTORY?filepfx=YOUR_FILE_PREFIX?begin=YOUR_BEGINNING_NUMBER?end=YOUR_ENDING_NUMBER?fileext=YOUR_FILE_EXTENSION" />

YOUR_DIRECTORY → the directory where you've uploaded your image files
YOUR_FILE_PREFIX → the prefix you've put on each file (optional)
YOUR_BEGINNING_NUMBER → the lowest/highest number in your series of images
YOUR_ENDING_NUMBER → the highest/lowest number in your series of images
YOUR_FILE_EXTENSION → the file extension on your files

What can you do with this? Well, my purpose for it was to make a header on a journal that changes every time you refresh. You can see an example here, but I'm sure you can find oodles of other uses for the trick. Have fun! If anyone wants the actual PHP script file, let me know in the comments.
