Indeed. You said you did output some filecontents, not the name of a fil=
e. =
In this case, there's practically no way the user wil ever be able to =
download the image. An HTML tag is NOT sending the image, it's just =
telling the browser where it can be fetched.
If you need an dynamically created image displayed only once, and not =
saved permanently as a file, point the HTML src attribute to a PHP scrip=
t, =
possibly with some GET variables, and let that script output an image, =
using the GD or ImageMagick libraries for instance.
