Image Block - Collage: How to add an additional image?

Site URL: https://demo104e25.squarespace.com

Hello all,

Does anyone know how to add an additional image to an image block - collage?

I currently have image 1 & 2 combined as 1 image, using the standard collage with an animation. I would like to be able to add an additional image to the back of the collage so that there is three "layers" that hopefully animate independently. See attached screenshots for clarification.

Thanks! 🙏

Can you share link to page where you use image collage? We can take  a look

I figured it out eventually lol. Thanks! Instead of adding a second image to the collage, I ended up adding an inline image block and then setting it behind the collage with negative padding.
