Append Image Size (Dimensions) to An Image File Name in Folder

In order to more easily see what size (dimensions) the embedded art is I like to save an image in the directory with the dimensions of the image appended to the file name so I can easily tell what images I'd like to find (or make) better artwork for - (ie AlbumArt_300x300).

Is there a way to do this in Bliss already?

Ideally I'd like to have the art embedded in each file + folder art "Cover.xxx or Folder.xxx" + an image labeled "AlbumArt_300x300".

Thanks
