Hey @vylla001
Thank you so much for coming to the Klaviyo Community for help with your popup signup forms.
In order to use dynamic images there must be event profile properties that you can use to to pull dynamic information into the image block when using our native signup form builder. However because this is a popup signup form it is typically only shown to your customers who don't have a profile and haven't been cookied by Klaviyo previously. Therefore there is no dynamic event data to pull from in order to display different images. Has any other Community members found a work around using a custom web feed? or using another third party integration to accomplish this?
If this functionality gets added, I will update you here on this thread of there is any update to share!
