Thank you so much for reaching out to Community! I totally understand how helpful creating a slideshow in Constant Contact would be. I apologize this is not a feature that is currently available. However, having a tool like this is feedback I would be happy to submit to our engineers. As a workaround I would suggest creating the slideshow in an outside source and connecting it to your email campaign through a clickable URL. Another option would be creating a slideshow as a GIF. If you chose to create a GIF we have this helpful article on how to insert a GIF into your email campaign. I hope these options are helpful to you! If you do have additional questions always feel free to reach out to us.
I've gotten several emails this season with slideshows and it holds alot of impact. I totally recommend it for CC- I would use it.
Thanks for joining us in the Community. I can certainly see how this would be useful. You are more than welcome to use the suggestions listed above and I'd be more than happy to pass along your feedback to our engineers.
