Dear Jerry,
I did call the base64_encode before storing the image in the database,
because as I mentioned before, when I 'save' the image with fwrite(),
the image opened with Gimp is perfectly working.
Sample:
$Data = base64_decode(image_from_db_encoded);
fwrite($fh, $Data);
And this works fine:
# gimp myimage.jpg &
If I do so:
header("Content-Type: image/jpeg");
print $Data;
It does not work.
For example, I've tested with sample image creation with gd, such as:
$I = imagecreate(256, 256);
$Bg = imagecolorallocate($I, 255, 0, 0);
imagejpeg($I);
It also does not work, why?
The GD is installed, even updated, phpinfo() sayz that everything is
okay, what is happening?
All the best,
Przemek
