i have an issue with site linking directly to my images. the problem is these images are generated on the fly with php/gd -- they're generated each time its viewed because i have done some watermarking manipulation and didnt want to watermaker them in a static way. they're including the images like this:
<img src=http://mydomain.com/script.php?pic=232">
not only is bandwidth usage increase but so does cpu because php/gd has to process them as well.. if they're including 5 or 6 of these images on a single page i can imagin how much cpu is being used.
how can i work around this, if at all possible?
Are you using apache? This might work in a .htaccess
Deny from all Allow from .mydomain.com Satisfy any
If that doesn't, maybe a rewrite rule that is normally used for media...

Try just changing/adding the php extension (don't know if that will work, but it's worth a shot).
