Step by step
- Decide the use/ratio: social square, vertical Story or print.

- Choose layout/spacing so faces/subjects are not cropped.
- Export 1200px+ PNG/JPG and check edges/margins.
- Clear likeness/image rights and privacy before posting.
Common mistakes

- Using unlicensed people/photos for commercial promotion.
Checklist
- Ratio matches platform/print.
- Photo count fits the cells.
- Faces/subjects intact with sensible gaps.
- Resolution is sufficient, no compression artifacts.
- Likeness/image rights and privacy cleared.
Key facts
- PNG suits text/transparency; JPG is smaller.
- Repeated exports accumulate compression.
