I am making a custom web part and need to be able to pull a picture thumbnail from a picture library. I am using SPMetal generated classes and don't see a way to do this.
It seems that thumbnails are put into a folder /_t and are changed to .jpg files with their extension appended with _ext.jpg but I was hoping that this value would exist somewhere.
So my question is how do I get the thumbnail source for a picture in a library? Prefer to use SPMetal classes (Even if I have to extend the class it is ok).
