I have pushed out the changes I recently discussed to my photo album software. Album preview images now utilize the new 16:9 size, making it easier for me to select nice looking previews. Several album preview images have been changed as a result. The collection preview images have also been modified. I plan on doing some more work on collection previews in the near future, to allow for varying image collage templates.
Please let me know if you spot something broken. I made a lot of changes on the back end in the midst of doing this upgrade; hopefully I squashed any bugs that got introduced.
