So here's tonight's progress. Give it a quick run through before continuing reading.
The cheesy looking title slide is in because one of the typical usage scenarios of this slideshow app is to be used in blog posts, if all the images of ALL the slideshows on a single page are downloaded without user interaction that'd be a waste of bandwidth.
The controls now have a lead header to show users that there's something waiting for them at the bottom of application.
Thumbnails are loaded first, then upon first viewing of the thumbnail the full version is queued for download.
This concludes my Silverlight exercise.
