Have you tried 0, 1, 2, 3 and 4?
They are all built-in and different sizes.

This should work, according to the docs...
Can the FreeSans.ttf file be read by the PHP user?

You are plain out of luck here.
There is NOTHING you can rely on for fonts installed at all, much less
where they will be.
You'd have to package them in with your own software to be safe.
And that may open up licensing/legal issues...

You could draw the image with a smaller font, and scale the whole
image up...
But that would usually not work well, as the scaling up has to
interpolate pixels, which rarely looks good...
You could also try using:
$font =
imageloadfont('/usr/share/fonts/truetype/freefonts/FreeSans.ttf');
if (!$font){
error_log("Unable to load font!");
$font = 5; //fall back to built-in font #5
}
ImageString($image, $font, $x - 20,$y-10, $text, $textColour);
