How to provide a default image file for ImageCache to use and process when the original does not exist?

Question

Is it possible to get ImageCache to use the default image? Or using htaccess to provide the default image for imagecache processing? Some of our client sites are> 4 GB, and this is very painful for all of their images that we do not need for development. I tried using htaccess, but ImageCache does not process the file and just ends up using file sizes that twist the layout.

Any thoughts?

Answer 1

As I understand it, ImageCache responds to a URI, for example

http://www.yourdomain.com/default/files/imagecache/set/images/pic.png

http://www.yourdomain.com - , files/imagecache - imagecache, set - , (: images/pic.png) - .

, pic.png , (default.png) ImageCache. .htaccess :

RewriteCond %{REQUEST_fileNAME} !-f
RewriteRule ^([^.]+)\.[gif|jpg|png]$ /images/default.png [L]

ImageCache images/pic.png, images/default.png, default/files/imagecache/set/images/pic.png.

  // Check if the path to the file exists.
  if (!is_file($src) && !is_file($src = file_create_path($src))) {
    watchdog('imagecache', '404: Unable to find %image ', array('%image' => $src), WATCHDOG_ERROR);

    $src = 'sites/all/modules/imagecache/sample.png';
  };
