This attachments plugin doesn't provide much enhancement to the display layer of Wordpress but it does provide utilities for theme builders to quickly extract all kinds of media into their themes. The use for which it was designed is galleries based on media uploaded to particular posts and pages.

Features

• Associate still frames with their appropriate videos and remove them from the images list.
• Separate videos from audio files, images and documents. 
• Provide methods for retrieving the first image or video.
• Simple cropping tools with simple defaults for both thumbnail and medium sized images.
• Provide an editors tool for re-parenting attachments.
• Extract Wordpress field names into sense-making keys (eg: post_extract becomes caption).
• Special methods for retrieving images globally by their caption or name.
• From v0.65 until Wordpress adds it to core, extract EXIF geo data (iPhone format currently) into metadata. [Based on the notes from kristarella]
