Looks like Imogen is her name... (May be slightly NWS) http://www.flickr.com/photos/peopleofplatt/sets/72157624572361792/
Don't think so. Imogen is a name, but it more typically describes a beautiful girl, or a fair maiden. Think it's just the description name of the album. If you look at the author's other albums, he typically describes multiple women using this term
It kind of seems like he did that on purpose. Also read the top comment. (If too lazy: RIP headphones mookie34545 1 month ago 23 )
