Editor: Split photo into a Mosaic

The current split image option with Image Options only splits a frame of a fixed size into columns and rows taking up the same space. It's good for multiple boxes but when an image is in the frame already, it just duplicates it the number or rows and columns, scaled to the smaller size.

A great feature for schools would be an option within this or a different function completely, to actually split the image. So its a mosaic tile. Each split frame is a portion of the full image. Top left corner, middle, right etc.

Hope people like this and can vote it up for a feature. thanks. Martin
