Can you give a live example? I can’t understand exactly what you’re trying to do.

Rotating? I don’t really understand what you mean. This script doesn’t rotate anything from what I remember and if you give it a landscape image for example and ask it to resize that in a portrait manner ( with cropping and stuff like that ), that’s what it will do. Please give more info on this.

Okay, I’ve adjusted it into 2 scripts, 1 for vertical, one for horizontal.
Both are working well, except the verticals come out horizontal, but the watermark placement & size is correct.
So I’m thinking I can add some php scripting to rotate the vertical images 90 Degrees CCW after watermarking.
However, I can’t seem to get it to work.
Any suggestions?
Thanks again for the great script.

Great Script!
It’s working great and is exactly what I needed.
However, for some reason, the script is rotating vertical (portrait) pictures into landscape format, then applying the watermark.
Why is it doing this?
I take it that it’s calculations are causing the problem. My watermark image is large enough to fit 52in. wide Landscape JPEGs @ 72dpi, so it’s really big, but resizes perfectly for smaller images, which is really all I need.
But I don’t need it to rotate the image for me at all.
Any clues on how to resolve this?
Thanks in advance for your help!

Hello,
Great Script!
However, the only problem I’m having is it’s rotating my vertical/portrait shots into landscape format.
I want them to stay portrait if they’re portrait.
Is this possible?
Thanks
Huck

Hi Mattias, image_jpeg() creates the watermarked image. On lines 36 and 38 in watermark.php you'll notice that function being used. imagejpeg() takes as third parameter image quality. For best quality use 100 as third parameter. More info on this function here: imagejpeg() official info

If you save watermarked picture, i notice the quality is now lower (smaller in size) as orginal JPG was.

ABCD0004.JPG (50,7 KB), watermarked and saved is only 39 KB, so lower quality. How can i preserve the same size/quality?

thanks

After 50 images or so it stops because probably the script reaches the script timeout period. Try increasing that or set set_time_limit(0) at the top of your php script.
To position the watermark on bottom right, replace this
/*
we establish the position of the watermark over the image
*/
$startwidth = ($imagewidth - $watermarkwidth) / 2;
$startheight = ($imageheight - $watermarkheight) / 2;

with this:

$startwidth = $imagewidth - $watermarkwidth ;
$startheight = $imageheight - $watermarkheight;

Heya,

The script works perfect but after 50 or so images it will just stop. Also how would i put the watermark image in the bottom right of every image instead of the middle? :)

Thanks
