Abstract: A system and method that images biological samples and uses chromophores to analyze the imaged samples. The chromophore analysis can be done by itself or in conjunction with fluorophore analysis in High Content Imaging systems. To perform chromophore analysis the biological samples can be labeled with different chromophores and imaged using transmitted light that is at least partially absorbed by the chromophores. To also perform fluorophore analysis the samples can also be labeled with fluorophores that are excited by excitation light. The chromophore analysis and fluorophore analysis can be performed separately or concurrently using a High Content Imaging system. The system provides the expanded capability by illuminating the chromophore-labeled samples with transmitted light of different wavelengths and automatically detecting the images which represent the differential absorption of the colored lights by the sample.

Abstract: Techniques to allow for ease of navigation within a photo browsing interface of a social networking system. In one embodiment, a designation of a first image for sharing is received from within at least one of a single-image view and a camera view. Based on the designation, the first image is added to a communication. The designation may be based on a user selection of an option provided by an interface of a mobile device.

In another embodiment, the privacy level of the communication and the designated images is based on the privacy setting of a user. The communication and the designated images may contain tag data identifying one or more people on a social networking system. In an alternative embodiment, the privacy level of the communication and designated images is adjusted according to the one or more people identified in the tag data.
