Image Quality
The {format} or extension of a requested image may utilize any of the following extensions to adjust for image quality and bandwidth requirements. Lower color images can be useful for mobile and visual displays which may have limited bandwidth or data transfer restrictions.
When utilizing a PNG image with 256 or less colors, dithering may be utilized to encode the color palette. For JPEG images, either the jpeg or jpg extensions may be used.
You can prefix any image quality type with @2x to request a higher DPI version for retina displays.
