Well, you don't sat why you don't like GD but that is what I use (on
one of my sites) so here is what I do---
When writing *to* the database:
A) You have sql LOAD_FILE to store a file (filesystem) in the db.
I write the GD image resource to a tmp file and then store it using
LOAD_FILE.
imagepng($img, $destfile);
/* stuff */
$query = "UPDATE table SET img_data = LOAD_FILE('$destfile') WHERE ?"
B) ??
When retrieving *from* the db:
A) The binary data is in the result set such that:
header("Content-Type: image/png");
echo $result['image_data']
-or-
You can create a GD image resource by using:
$img = imagecreatefromstring($result['image_data']);
/* GD manipulations */
header("Content-Type: image/png");
imagepng($img);
either should output an image to the browser.
B) output_buffering lets you do some crazy stuff.
-or-
Take a look at the Imagick module for PHP (PECL).
