Access Php code when Image is loaded

[stanfish]

I wonder if it is possible to access php page and load an image by a HTML expression like <img src="a.php?id=123">. It will access the page a.php with the GET parameter id=123 and the php page will output an image a.jpg.

Does anyone know if it is possible to do that? If so, how to write the code to output the image? Otherwise, does anyone have any alternative solution?

Thanks!

All you'd need to do is use [man]header/man to declare the necessary Content-Type of the image, and then output the image data (be that with [man]readfile/man, [man]file_get_contents/man, [man]fopen/man/[man]fread/man, ...).
