Screenshot tips
Use an original PNG at 100% game interface scale, with complete icons and opaque backgrounds. Bank, preset, inventory and Grand Exchange (GE) screenshots are supported. Don't resize the image. Worn-equipment views aren't supported.
Crop large screenshots to the icons you need: maximum 2048 pixels per side and 6 MB. Up to 28 icons can be detected; you can submit 10 at a time.
