Image resize and Wallpapers Mod

[jaywilliams+]

I got the mod to work with EXIF now.

Here is what I did:

PHP Code:

function resizeimage($args) {

...
 
    if ($ext == 'jpg' || $ext == 'jpeg') {
      $img = @imagecreatefromjpeg($image_path);
        } else if ($ext == 'png') {
        $img = @imagecreatefrompng($image_path);
        } else if ($ext == 'gif') {
        $img = @imagecreatefromgif($image_path);
        }
    
// Added:        
// Creates a copy of the image with the the suffix _orig added to the end
        exec("cp " . $image_path . " " . $image_path . "_orig");
        echo "$image_path";
            
...

    imagejpeg($img, "../images/$file");
    $resizedimage = "../images/$file";
//Added:
// This makes the image writable, and then copies the EXIF data from the original image, then deletes the original.
        chmod($resizedimage, 0777);
    chmod($resizedimage . "_orig", 0777);
    exec("/home/...{path to jhead}.../admin/jhead -te " . "./" . $resizedimage . "_orig " . "./" .$resizedimage );
    exec("rm " .  $resizedimage . "_orig");
// End of EXIF fix
    chmod($resizedimage, 0644);
    echo "$resizedimage";
    
    } 


Hope that helps.

I just downloaded the Pre-built Linux executable of Jhead, placed it in the ./admin/ directory, and set the chmod to 777.

Enjoy

chmod the jhead file... not the admin folder. my bad.

Hi Everybody.

First, I would like to thank utoks for his hack : it avoids me to do the job :-)

Is there a way to keep EXIF information without using jhead ? My web account doesn't support it, and I can't execute the linux binarie file.

If someone has an idea...

ah so I see you've figured out the EXIF issue, jay. Im sorry i did not get back to you earlier.

I tried out your modification to the wallpaper mod. Im still not getting exif data on the resized images. but i have a feeling that is because exec() doesnt work on my server. I asked my <a href="lunarpages.com"> hosts</a> to switch me to an exec() enabled server so ill try it then.
(it should be noted that i applied your code to the 1.4.3 index file that i just updated to work with the wallpaper mod, however i doubt that would change anything)

Meanwhile- im going to include just the non exif modded index.php for 1.4.3 for the next release. Once they switch me to an exex() enabled server ill figure out the exif stuff and then release it.

Here is the new mod file for 1.4.3: http://www.pixelpost.org/v1/index.ph...ads&details=64

Hi,

I changed a bit the behaviour of your mod, because of my EXIF problem. Now, it works like this :
- you post your picture, wallpaper sized.
- pixelpost resizes the picture at the display size
- You have now two versions of the picture : wallpaper and "normal" display.
- If there is no EXIF information inside the normal display picture, it will read the information inside the wallpaper picture.

Let me know if you are interested by the mod.

yod,

I'm interested in your mod.. that's a great workaround. Is there anywhere to download it or modify the script?

Thanks.
