@photocrati,
I’ve made a very nasty workaround to create a right sized picture for the widget.
What I did, since I have no knowledge of how to create a module for wordpress, I wrote a php snippet which I call from your widget.
As I said, it’s a nasty hack but if you could make something similar – that would be great. It saves the need to download a full size image and scale it within the browser.
The code:
<?php
/***************************************************************************/
/* Ugly workaround to display the front small picture better then intended */
/***************************************************************************/
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
header("Content-Type: image/jpeg");
$baseDir = '/var/www/html/'; // Base wordpress dirctory
$cleanDir = '/wp-content/gallery/'; // Make sure no-one is trying to hack us
$targetWidth = 250;
$targetHeight = 250;
$path = parse_url($_GET['url'], PHP_URL_PATH); // Get the path out of the full image location
$path = str_replace('..', '', $path); // Remove any .. from the path, to eliminate use of parent dir
if (strstr($path, $cleanDir)) { // Making sure path include our hard coded value
$filename = $baseDir . $path;
if (is_file($filename)) { // Last check - is it a file?
$size = GetImageSize($filename); // Get the original picture dimentions
$originalWidth = $size[0];
$originalHeight = $size[1];
$ratioW = $targetWidth / $originalWidth; // Check the best way to resize
$ratioH = $targetHeight / $originalHeight;
if ($ratioW < $ratioH)
$ratio = $ratioW;
else
$ratio = $ratioH;
$newWidth = $originalWidth * $ratio; // New dimentions
$newHeight = $originalHeight * $ratio;
$source = ImageCreateFromJPEG($filename);
$target = imagecreatetruecolor($newWidth, $newHeight);
ImageCopyResized($target, $source, 0, 0, 0, 0, $newWidth, $newHeight, $originalWidth, $originalHeight);
imageinterlace($target, true);
ImageJpeg($target, NULL, 75);
ImageDestroy($target);
ImageDestroy($source);
}
}
?>
The call from the original widget, from:
src="<?php echo esc_attr($storage->get_image_url($image, $settings['show'])); ?>"
to
src="/wp-content/additions/createthumb.php?url=<?php echo esc_attr($storage->get_image_url($image, $settings['show'])); ?>"
