Claim Text:
1. A method performed by a media reproduction device, comprising: compressing, by the media reproduction device, an image into first tiles to create a compressed image; generating a table of contents (TOC) that links the first tiles together, the TOC including metadata indicating how the first tiles are to be processed for subsequent display; displaying, on the media reproduction device, a first thumbnail of the image; decompressing a first subset of the compressed image that corresponds to a first command received at the media reproduction device without decompressing an entirety of the compressed image; processing the decompressed first subset of the compressed image based on the metadata as the first subset is decompressed, the processing including at least one of orthogonal rotation, vertical mirroring, horizontal mirroring, image masking, image fills, alpha-blending layers over background, or arbitrary layer placement; adding, by the media reproduction device, new content based on the first command by rendering and compressing the new content into second tiles without modifying the compressed image; linking TOC entries for the second tiles into the TOC; displaying, on the media reproduction device, a modified thumbnail of the image that includes the new content; determining whether a second command has been received for executing on the modified thumbnail; and in response to determining that the second command has been received for executing on the modified thumbnail, decompressing a second subset of the compressed image that corresponds to the second command without decompressing the entirety of the compressed image.
