Microsoft's solution is the following piece of code after your ShowDialog():

VB
If SaveImage.FileName <> "" Then


That checks to be sure their is a file name selected. Here is a link to the article:

I understand the problem is when you hit cancel. That is what the line of code above prevents. You check to see if a file name was selected. If that field is empty, you don't attempt to save the file and you are good (no error). Your error is occurring because your user is hitting cancel and then you are trying to read the file name they never selected.
