Storyline 3: Media in Marker (Label)

Hello Allison,

I'm sorry to hear that you ran into this snag. I can confirm that I was able to replicate the behavior in Storyline 3 and Storyline 360, and I was able to match it to a known issue that we are currently tracking where duplicated markers show the same zoomed out picture, when more than one of them have inserted images with the zoom picture turned on.

The fix is to add markers one at a time instead of using "Copy + Paste" to add more markers. I can confirm that using the "Insert -> Marker" functionality each time you need to add a marker allows the markers to display their corresponding images correctly. I've attached a sample file so you can verify if this fix will work for you as well.

As for changing the size of the picture in the label, you can first increase the size of the label area, click on the image, and then finally 'click and drag' on the white boxes that appear to increase the size of the image: 

Hope this helps!
