But I can only get one image?

Yes. If you try to do multiple IMG tags to get more than one, your web browser will display the first one it got over and over again... since it thinks its the same thing.

There IS a cute way to trick it though. On each call to the cfimageget.php URL, add in a random parameter. If you change for each image call, you will keep getting different images.

For example, these would generate three different ones... the last two would show the same image, since they are the same call.
