Resize Image

[L33TRB]

Hope this comes under the right section,

Anyway i'm looking into some sort of image resize, When members post pictures up on forum the image resizes to a non large image.

Anyone know of where i can get info on this, also its for phpbb3

Don't know how good your php is - but here is a routine i wrote for an ecommerce web site hosting i created. It takes an original picture and creates a medium and a thumbnail sized copy and saves them in appropriate places

PHP Code:

function resizeImage($img, $imgPath, $quality,$medPath,$thumbPath) {
    // Open the original image.
    list($width, $height, $type, $attr) = getimagesize($imgPath.$img);
    //create new file name
    $baseName = explode("_",$img);
    $newNameE = explode(".", $img);
    //medium image
    $newName =  $baseName[0] . '_med.'. $newNameE[1] ;
    // Determine new width and height for medium image
    if ($width>$height) {
        $newWidth=120;
        $newHeight=120*$height/$width;
    } else {
        $newHeight=120;
        $newWidth=120*$width/$height;
    }
    // get the image
    $original=createimage($imgPath.$img);
    // Resample the image.
    $tempImg = imagecreatetruecolor($newWidth, $newHeight);
    if (!$tempImg) {
        return false;
    } else {
        if (!imagecopyresampled($tempImg, $original, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height)) {
             return false;
         } else {
            // Save the image.
            if (!saveimage($tempImg,$medPath.$newName, $quality)) {
                echo ' Problem with medium '.$newName;
                return FALSE;
            } else {
                // Clean up.
                echo ' Med <a href="'.$medPath.$newName.'" target="_blank">'.$newName.'</a>';
                imagedestroy($tempImg);
            }
        }
    }
    // thumbnail
    $newName =  $baseName[0] . '.'. $newNameE[1] ;
    // Determine new width and height for thumbnail image
    if ($width>$height) {
        $newWidth=72;
        $newHeight=72*$height/$width;
    } else {
        $newHeight=72;
        $newWidth=72*$width/$height;
    }

    // Resample the image.
    $tempImg = imagecreatetruecolor($newWidth, $newHeight);
    if (!$tempImg) {
        return false;
    } else {
        if (!imagecopyresampled($tempImg, $original, 0, 0, 0, 0, $newWidth, $newHeight, $width, $height)) {
            return false;
        } else {
            // Save the image.
            if (!saveimage($tempImg,$thumbPath.$newName, $quality)) {
                echo ' Problem with thumb '.$newName;
                return FALSE;
            } else {
                //Clean up
                echo ' Thumb <a href="'.$thumbPath.$newName.'" target="_blank">'.$newName.'</a>';
                imagedestroy($original);
                imagedestroy($tempImg);
            }
        }
    }
    return true;
}

Thanks My phpbb skills arent up to much, where exact do i put this

[DavidAllen]

I don't know phpbb - so can't help you as to exactly where to put it. It would need to go in the bit where the uploaded images are processed. If it's too much for you, it might be better to follow the link Brian gave as that appears to be some sort of pre-packaged mod for phpbb
