Suggestion: prefix generated filenames

[mgussekloo]

Generated filenames using the 'resize' filter are generally filename_[width]x[height].jpg. This makes it hard to tell them apart from "original" files in the uploads-folder.

I made a filter called 'prefix' that prefixes a filename. I use it to rename all my resized files, so they are 'resized_filename_widthxheight.jpg'.

I was wondering if anyone would find this useful. It might be standard behavior of the resize-filter.

 $twig->addFilter('prefix', new Twig_Filter_Function(function($src, $prefix) {
	        $oldFile = ABSPATH . TimberURLHelper::get_rel_url($src);
	        $newFilename = dirname($oldFile) . '/' . $prefix . basename($oldFile);
	        if (file_exists($oldFile) && !is_dir($oldFile) && !file_exists($newFilename)) {
	            rename($oldFile, $newFilename);
	        }
	        $newSrc = dirname($src) . '/' . $prefix . basename($oldFile);
                return $newSrc;
  }));

@gchtr I also think Timber resized images should live outside the uploads folder (I'm actually dosing this in my own Timber implementation) but let's discuss this when we'll be replacing the image resize part from Timber :)
