Abstract
Provided are methods and systems for generating multiple versions of an image and providing the appropriate version of the image to a user device based on a display characteristic of the user device. If a higher-resolution source version of an image exists in the sprite directory, that higher-resolution version of the image is built into a mixed-resolution sprite sheet rather than a standard-resolution sprite sheet. A Device-Pixel-Ratio for a user device is utilized when determining the appropriate version of an image to send to the device, where the Device-Pixel-Ratio is defined as the ratio between physical pixels and device-independent pixels (dips) of a display of the device. If the Device-Pixel-Ratio is equal to or greater than a threshold value, a high-resolution version of an image (if one is available) is sent to the user device. Otherwise, the standard-resolution version of the image is sent to the user device.
