Slides per post
A single listing photo tells people what a house looks like. A before/after carousel tells them a story — and stories are what get someone to stop scrolling, swipe, and actually read your caption.
People don't share photos.
They share transformations.
The format is simple: slide one is the "before," slide two is the "after," and everything past that is optional context — a detail shot, a caption card, a call to action.
Same angle. Before, then after. Let the contrast do the talking.
