The feature

I have a bunch of extra long and extra wide images that are included in my photo collection. Sometimes these images are incredibly long and/or have words and details that aren't visible. Within the slideshow feature, it would be great if instead of fitting all of it onto the screen, the image would slowly scroll the image from left to right or top to bottom, and then move on to the next image after the standard pause time.

The generic Mac photo screensaver does the left to right scroll, but for some reason goes from bottom to top which doesn't make any sense in terms of say, a comic strip that reads from the top down.
