Hey @j.singler, welcome to the community!

You can definitely show the abandoned cart item image (or any dynamic image) in a text.  Just remember, an image is technically an MMS so it’ll cost you additional sends. 

• Add an Image like you would normally.
• Instead of choosing an image or uploading an image, select the “Dynamic Image” option
• In the text field, add the event property that has the image source URL.
• Add any other text as you normally would, you can use event properties here too.
• Make sure to test and preview it before setting the Flow live!

Klaviyo has a pretty good step-by-step documentation linked below, and their example is literally for an abandoned cart product image! Also, the second link gives you some more info about SMS vs MMS:

• How to Add a Dynamic Image to a Text Message
• The Difference Between an SMS and MMS

 Hope this helps!
