To sliko je mogoče poustvariti z uporabo vektorske grafike kot SVG-datoteko. To ima več prednosti; več informacij je na razpolago na strani Commons:Media for cleanup. Če je SVG-oblika te datoteke že na razpolago, jo, prosimo, naložite. Potem, ko boste SVG naložili, to predlogo zamenjajte z izrazom {{vector version available|ime nove slike.svg}}.

Ta geology slika je bila naložena v formatu JPEG, čeprav sestoji iz nefotografskih podatkov. Te informacije bi bile bolj učinkovito ali natančno shranjene v formatu PNG ali SVG. Če je mogoče, naložite različico PNG ali SVG te slike brez artefaktov stiskanja, izpeljanih iz ne-JPEG vira (ali z odstranjenimi obstoječimi artefakti). Ko boste to storili, označite JPEG različico z {{Superseded|NewImage.ext}} in to oznako odstranite.. Ta oznaka naj se ne uporablja za fotografije ali preslikave. Za več informacij glejte {{BadJPEG}}.

Caption: Coral atolls develop from reefs fringing volcanic islands. As first hypothesized by Charles Darwin, and confirmed by ocean drilling done by British scientists a century ago, reefs fringing volcanic islands build vertically to sea level, forming steepwalled barrier reefs. As a volcanic island subsides, or sinks, with time, the growing reef keeps pace with the rising water level. When the island eventually submerges, the ring-shaped reef forms an atoll with a central lagoon.
