How to display multiple images in date sequence by file date?

[Joseph Sinclair]

To do something like that you're probably going to need to use image magick or a similar tool.

It sounds like you want to do a contact sheet or filmstrip rather than a slideshow.

The Image Magick "montage" command is made for this purpose, it's documented here: http://www.imagemagick.org/script/montage.php
You'd replace the for loop with something like this:

montage $(ls -1t) -tile x1 ../filmstrip.png

(note, I use the number 1, not the letter l in the option to ls, I mistyped last time).

That would create a single output image (probably large) with all the input images lined up.  You could follow that with a display command and, optionally, delete the filmstrip if you don't want to keep it.
It could take a very long time to generate and display that filmstrip at full size, so you might want to resize the images at the same time:

montage $(ls -1t) -tile x1 -size 512x512 ../filmstrip.png

There are a ton of other options (including -coalesce if you really just want an animation of the images), so it's worth reading the documentation.
