## Description

GUPnPDLNAImageInformation holds all image metadatas important for matching profiles. Note that it does not mean all data should be provided for every image file as in some cases it does not make sense.

For metadata attributes that do not exist in current image file an unset value should be returned. For metadata attributes that do exist a set value with proper underlying value should be returned. In case metadata extractor has completely no clue how to extract some metadata attribute at all, an unsupported value should be returned. Note that unsupported values should be a temporary mean before fixing the multimedia framework to be able to extract such attribute.

Note that `gupnp_dlna_image_information_get_mime()` should always return a set value. Otherwise it is highly probably that the file will not match against any DLNA profile.
