Here a small and rapidly written application that displays weather
charts (wind-strength and wind-directions) for several regions in the world.
Clicking on one of the buttons on the left preloads and displays the
images of the matching region. Navigation with the slider or watching a
slideshow. Speed can be adusted.

On the server a little Delphi app is running which collects one chart
per day and region and stores it together with a simple text file that
contains all filenames for each region.

The sources with a selection of 30 images per region:

You have to register the included theme "Office blue.wbt" before opening
the project.
