Well that's a lot of questions.
Here's an alternative to the GetThumbnailImage function so you don't have to
deal with its limitations:
http://www.devx.com/dotnet/Article/22079

As far as displaying the thumbnails in an organized way, I experimented with
repeaters and other such techniques, but ultimately went with a Table
control. The process is a bit more manual but it gave me all the
functionality I could ever want, and it's quite logical and intuitive.
I basically just looped through my images and dropped each one into a new
table cell object.
