What does this do?
Shows a random image.
How do I use it?
Just insert the tag into your template/page like: {random_image}
What parameters does it take?
(optional) folder - ("
http://www.scotwellhouse.com/uploads/im ... m/img1.jpg").
(optional) height - Image height (579px).
(optional) width - Image width (default is unspecified, eg. actual image width).
(optional) align - Image alignment (default is unspecified).
(optional) alt - Image description/mouse-over text (default is image file name).
(optional) id - Image id (default is unspecified).
Hints and Tips
-A good idea might be to organize your random images in folders (ex): uploads/images/random/pagename/ a.s.o.
-Specifying width and not height (or viceversa) prohibits your images from exceeding that certain width (or height). Pretty useful sometimes.
-Thumbnail images are automatically excluded (images starting with "thumb_")

Thanks to Greg for hinting on the ID-tag
Version: 1.2
Change History:
1.0a - Alpha version released.
1.0 - Added ALT-tag. Changed default values for Height, Width and Align
1.1 - Images starting with "thumb_" (thumbnails) prevented from being displayed
1.2 - Added ID-tag and changed IMG tag to comply with W3C standard. Also fixed a bug where the same image was selected when you had several random images on the same page.
