Only some of my signatures are showing as images in the Grid View Report

I asked previously, but the answer I got from a jotbot person wasn't there....so I"m asking again with their response..

In Grid View of results, why are some of the signatures showing as images and others only have a microscope icon that you have to hover over to see

I tried to see if it had to do with what device was used, but there is no pattern. 

Help! I want to purchase this monthly, but if they don't display like that, then no...

thank you!

The RESPONSE: 

The signatures are saved as an image therefore, you need to check the option to show the images instead of a link in the grid settings. I've fixed it for you.

MY RESONSE:

so I got a response but I'm still confused, Where is the "show image option" for the report?  m still confused.....

can you tell me where you see that?  All I see is this when I go to "add new report" and select Grid report....

and if it's in the settings of the report, why are some of the images showing and not the others?

IS that a setting some place else?

thank you for getting back to me... I'm trying to decide if our school will be using this program
