20205	Add the ability to filter wp_get_attachment_image()	helgatheviking		"i'm working on a plugin that lets users define any image to serve as the thumbnail for any PDF document.  I'm storing the ID of the image as post_meta for the PDF attachment.  Instead of showing the default icon with wp_get_attachment_image() I'm quite close to being able to do this by filtering image_downsize.

the trouble is that the image_downsize filter it run ''after''


{{{
if ( !wp_attachment_is_image($id) )
		return false;

}}}

so the PDF image fails the test and I never have a chance to run my filter.
