RandomImage

This script calls a random image from a defined folder ignoring folders and thumbs.db file. Uses <?php include(); ?> to display the image. Questions and comments should be directed to Marcus (marcus -at- artitumis -dot- com).

# Random Image Generator 
# This script will scan a directory of your choosing, ignoring folders and 
# the dreaded Thumbs.db file and then return a randum image from the specified 
# folder. Easy to customise and use :-) I recommend using include() with this.

# I don't know if I am just retarded or what, but this didn't work exactly how I 
# wanted. I edited a couple of things and it worked perfectly.

# $dir is your system path to where the script file sits (this is not your url) 
# $path is the url path to where the images sit 
# 
# Use <?php include('path/randomimg.php'); ?> replaceing path with the url path to where the 
# images sit to call your image.
