Pagination of images - varying number of images depending on orientation

[chuckylefrek]

I have read alot of messages about basic pagination. However none appear to deal with the issue where the number of items to be displayed on each page varies. In my case, I am creating a thumbnail gallery of product images. The images are either landscape or portrait, and the page may conntain a mixture of the two. Therefore depending on the orientation of the images, the total amount of images that can be displayed on the page will vary.

 

I would appreciate advice on how best to implement pagination for this scenario.

 

Here is the page that currently does not have any pagination
