Each of the results contained within emailTest.Results can be used to display capture images to your users. There are a few things to check before attempting to us the *Image properties of a result:

Has the result completed? 

If your result's Completed property is true, it is safe to use the result to find its images (covered below).

Is the result a type with captures?

If result's ResultType property is "email", it will have capture images. If it's "spam", it won't.

If the answer to the above questions is "yes", then you can move onto deciding which properties contain the capture images you want.

Choosing the right images

If your result's SupportsContentBlocking property is true, you should use the following properties:

WindowImageNoContentBlocking

WindowImageContentBlocking

FullpageImageNoContentBlocking

FullpageImageContentBlocking

WindowImageNoContentBlockingThumb

WindowImageContentBlockingThumb

FullpageImageNoContentBlockingThumb

FullpageImageContentBlockingThumb

If SupportsContentBlocking is false, you should use the following properties:

WindowImage

FullpageImage

WindowImageThumb

FullpageImageThumb
