PHP echo image

Hi, I am using soehting like: site.com/pic.php?picture=picture.gif
and on pic.php
I want to display "picture.gif"
I can do this using <img src="$_GET['picture']" alt="" />
But I also want to be able to use an HTML image on another page to be able to view it.

So on site2.com I want to be able to sue: <img src="ite.com/pic.php?picture=picture.gif" alt="" /> and the picture to be displayed.
How do I do this?
It works if I echo out the image source in php using file_get_contents, but if I go to pic.php it shows the source and I want it to show the image

 

You will need to set the correct mime type for your picture in the headers.

 

on top of everything place

header("Content-type: image/yourimagetype");

PHP:

for example, /png, /jpeg, /gif
