OPF Image Treatment
Rounded Card
An image sits inside a rounded rectangular frame with optional shadow, giving screenshots and photos a contained surface.
Best Fit
Product screenshots, app previews, feature slides, and structured comparison pages.
Photography Guidance
Use screenshots or photos with clear internal margins. Avoid adding a heavy frame around already cluttered UI.
Avoid
Avoid stacking multiple framed images unless the layout is explicitly a comparison or gallery.
Treatment Practices
Use a subtle border radius and shadow rather than a heavy decorative frame.
Keep the card aligned to the same grid as surrounding content.
Use contain for screenshots when no content can be cropped.

General Image Rules
Crop with intent
Choose fit, position, and size based on the subject and message, not just available space.
Protect readability
Text over images needs enough contrast, an intentional overlay, or a separate text surface.
Respect image truth
Avoid filters or crops that distort evidence, screenshots, charts, or compliance imagery.
Keep a system
Use a small set of image treatments consistently so photo-heavy decks still feel coherent.
