What you have below is the usual way to do it... if you want to get a bit fancier you can have your getimage.php script do something like this (pseudo code):
------------------------------------------------------------------- figure out what image to display via the $id if /path/to/image/cache/$id exists then just spit that file back to the browser and exit otherwise... generate the image and write it out to /path/to/image/cache/$id and spit it back to the user. ------------------------------------------------------------------- This has the advantage that you only need to dynamically generate the image once and all subsequent visitors will get the cached version and in general things will be faster. If they change somewhat (once a day or whatever) you could add some logic to remove old entries, etc.. good luck! On Thu, 13 Jun 2002, Shane wrote: > Kevin...
