Hello ​@Franco ,

Thank you for posting!

Would you mind clarifying exactly how you are extracting the thumbnails? Also, have you checked that the thumbnails are not sitting 'behind' the frame itself?



I believe you're saying that you have done the following, is that correct? 

1) Integrated a Google Slide deck

2) Extracted some thumbnails for each slide from the deck 

3) Placed a frame around those slides

4) Hidden some (not all) of those frames

Issue: When you un-hide a frame the thumbnails are not present.

Additional help on frames:
Frames don't necessarily have background images, but they can have background colors. You can first click a Frame you want to add a new color to. Then select the fill color or line color icon from the Frame’s Context Toolbar. In the window that appears, select a color from the options. You can set a custom color by selecting the plus icon.
