Bookmarking Question

I just finished building a small project in Cap 9.  I built a sort of TOC slide that gives the learners the ability to click on a picture/click box and that takes them to another slide to watch a video.  After the video, it takes them back to the TOC screen where there is an image of a check mark showing complete.  It also disables the click box that they initially clicked on.  My problem is if I exit them module and get back in, it does bookmark, however the check mark image goes away and the box is clickable again.  Is there a way to have the image stay on the screen once the learner comes back in, or is this the way it is?  Thanks!
