The simple screen view image can be created by selecting File / Export / 2D Image and in the "Save as file type" dropdown choose JPEG. This will immediately save your screen image.
I suggest that you use this thread to post examples of final images you are pleased with but use the "Looking for Help?" sections if you have questions.
