[Plugin: Dynamic Image Resizer] Images with special characters are not resized

Hi,

Great plugin! It saved me a lot of MB’s!

There are two things that may be improved:
1) Images with special characters in their filenames are not resized because the url is not decoded first. I found that changing line 19 from
$filename = $matches[1].'.'.$matches[5];
into
$filename = urldecode($matches[1].'.'.$matches[5]);
fixed that problem.

2) The plugin uses the character ‘c’ at the end of a filename to indicate it needs to be cropped. This didn’t work for the images I had already uploaded before I installed the plugin. Maybe you can think of a solution for this. I fixed it by deleting all the resized images WordPress had created before. Then I changed the filenames in the metadata by running the following script:

$args = array(
    'numberposts'     => -1,
    'offset'          => 0,
    'category'        => NULL,
    'orderby'         => 'post_date',
    'order'           => 'DESC',
    'include'         => NULL,
    'exclude'         => NULL,
    'meta_key'        => NULL,
    'meta_value'      => NULL,
    'post_type'       => 'attachment',
    'post_mime_type'  => NULL,
    'post_parent'     => NULL,
    'post_status'     => NULL );
$attachments = get_posts( $args );
foreach ($attachments as $attachment) {
	$meta = (get_post_meta( $attachment->ID ,'_wp_attachment_metadata'));
	$meta_new = $meta;
	$sizes = $meta[0]['sizes'];
	if ($sizes) foreach ($sizes as $size=>$value) {
		if (in_array($size,array('thumbnail', 'post-thumbnail', 'featured-image'))) { // put your images that need to be cropped here
			$filename = $value['file'];
			if (!preg_match('/(.*)(c).(jpg|png|gif)/i',$filename) ) {
		   		if (preg_match('/(.*).(jpg|png|gif)/i',$filename,$matches) ) {
					$newfilename = $matches[1].'c.'.$matches[2];
					echo 'Found: '.$newfilename."\r";
					$meta_new[0]['sizes'][$size]['file'] = $newfilename;
				}
			}
		}
	}
	update_post_meta($attachment->ID,'_wp_attachment_metadata',$meta_new[0]);
}
