[RESOLVED] Outputing image directly

Opimus

Instructions say: If you don't provide the second parameter (which I don't) , imagepng() sends the PNG-formatted picture straight to output

<?php
	$brush = imagecreate(100,100);

$brushtrans = imagecolorallocate($brush, 0,0,0);
imagecolortransparent($brush, $brushtrans);

for ($j = 1; $j < 18; ++$j) {
	$color = imagecolorallocate($brush, 255, $j*15, 0);
	imagefilledellipse($brush, $j*5, $j*5, 5, 5, $color);
}
imagepng($brush);
imagedestroy($brush);
?>

Unlegible "HTML" that's being output from above code (GD extension enabled):

&#65533;PNG  &#65533;&#65533;&#65533; IHDR&#65533;&#65533;&#65533;d&#65533;&#65533;&#65533;d&#65533;&#65533;&#65533;G<&#65533;&#729;-&#65533;&#729;&#65533;&#729;&#65533;&#378;QuÜ&#65533;&#65533;&#65533;tRNS&#65533;@&#263;&#344;f&#65533;&#65533;&#65533;ëIDATx&#65533;í&#323;&#357;&#65533; &#340;P&#273;&#351;&#729;&#731;&#379;¸&#378;"Š&#268;§&#268;&#731;&#282;&#355;î3&#65533;&#65533;WžORp&#258;y&#733;&#65533;&#324;&#328;&#280;&#369;J n8O&#728;a&#65533;W&#262;&#65533;Üp&#65533;DÝ0:&#379;ô.)¸á<&#65533;&#258;xx&#314;y$7&#65533;'&#323;m7&#379;Ü&#711;¤&#341;&#65533;ó$&#351;&#259;â&#65533;ë&#65533;Üp&#65533;D§a&#65533;&#378;r&#65533;&#65533;&#65533;Î&#65533;¨F&#259;&#65533;Ö$7&#65533;'Q5&#65533;&#280;+&#318;J n8O&#728;b&#65533;WJ&#65533;Üp&#65533;D&#65533;a&#378;r&#65533;&#65533;Î&#65533;h7&#65533;&#65533;Wö]Rp&#258;ye&#258;&#268;&#378;&#65533;&#322;¤&#341;&#65533;ó$J&#65533;&#65533;x%%IÁ çI´&#262;&#262;+&#368;&)¸á<&#65533;V&#258;Xye]%7&#65533;'&#322;&#366;l÷&#377;&#65533;&#262;&#313;X&#379;Ç&#65533;&#65533;&#65533;&#65533;IENDŽB`&#65533;

I feel so silly:o

That's not HTML being outputted - that's the raw image data being outputted.

Your browser, however, doesn't know this - you need to use [man]header/man and specify the appropriate Content-Type header.

scross

Add:

header('Content-Type: image/png');

to the top of your code. This tells the browser to treat it as a PNG image rather than HTML.

Works now. Thank you, thank you!
