switching width and height field positions.
tnx, m3avrck(http://drupal.org/user/12932)

change the return value of _imagecache_get_presets() to be more select friendly ($id => $name).
fixed up the url generation in theme_imagecache.

file_directory_path in the path for the imagecache menu callback,
added a theme function, theme_imagecache($namespace, $path) to make it a little easier
to use and to construct urls using file_directory_path.

Hope this makes life easier for some of you...

.darrel.

fixed.

Right now its all about imagecache_cache. Once its working we're functional.

should be super.

Add check for op='Add Crop', and 'Add Resize'....
Leave interesting possibilities for later. (watermark, grey scale, sepia, warp, etc).
