Question : Handling Images in Silverlight

Hi to all,

I am working on a silverlight application and I was wondering what the best way is to handle images in Silverlight? It is very similar to the following site:
http://www.vertigo.com/slideshow.aspx
I downloaded the sample and found that the image thumbs are no bigger than 200 KB. When I upload my Images and create thumbs for the images they are distorted and DO NOT LOOK GOOD!!!! Below is a sample of my code I use, but this is for bulk resize. When I upload I just replace the bulk upload with a single filename.

How can I resize images with a size between 1.4 meg to 2 meg to thumbnail size and not distort them and how will I handle the smaller images in Silverlight where it still looks good?

Thanks

You'll need to add a library to be able to control the image compression you want. FJCore is a common one used for this:
