A quick heuristic for deciding which product features earn space in an image (callout, infographic icon, or comparison row): (1) do shoppers actually care about this feature, and (2) how quickly will they understand it at a glance? A feature that fails either question — niche specs, jargon, or benefits that need explanation — gets cut rather than crammed into a Multi-Use Call-Out Image or infographic.
This is the image-specific counterpart to the Benefit-Over-Feature Bullet Point Litmus Test used for bullet-point copy: both exist to stop sellers from dumping every spec onto the listing and instead force a cut down to what actually moves a purchase decision.
