Imagecache External for Drupal 7

Ok, will post a patch if the need of this module is confirmed for the project I am working on.

Okay larowlan,

Here is a patch to port Imagecache External to D7.

I used 6.x-2.0-beta2 as starting point, but I discovered a major design problem: if there is an error fetching an image (no permission, 404), the module sends a drupal_not_found() or drupal_access_denied(), the problem is that happens on the page request on witch we try to display an image (resulting in broken page display), not the image request itself.
I really understand the point to not bootstrap Drupal on each external image request, so I added a theme_imagecache_external() function witch acts as theme_image_style(). If something is wrong, no img tag is returned.

Other points to review:

So with this patch, the recommended way to display an external image is:

<?php 
  print theme('imagecache_external', array('path' => 'http://larsjung.de/h5ai/sample/screenshots/h5ai-v0.7-icons.png', 'style_name'=> 'thumbnail')); 
?>

This will return a formated img tag, gaining D7 features:

  <img typeof="foaf:Image" src="http://example.com/sites/default/files/styles/thumbnail/public/imagecache/thumbnail/externals/8d064b159ef9232fbeb533dfa1698a2b/filewkhOsZ" alt="">

oops, did not seen issue #1181232: Prevent image request errors from bubbling up to the entire page. ... Luckily the orientation is the same..

You're welcome!
