Create a php file that:
starts a buffer
reads blob from db into buffer
sends a content-type header of the same type as image
flush buffer
then load image in your template like so:
<image src="myDbImage.php? someparameter=somevalueusedtopulltheimag
e"/>
there are examples of how to write an image stream out to the browser in
google.
This is the php file that you put in your image tag. Make sure you
get the content-type header correct. Don't let the browser figure this out
on it's own or you are asking for trouble. You can't do this inline in a
page, the image puller/generator needs to be it's own file because it
needs to send a content type header that's not text/html.
