What does the ImageInfo plugin do?
Zoom Search Engine v5.0 introduces a new feature that allows users to search for images such as photographs and diagrams. Searching is carried out by using metadata associated with the file. Image files like JPEGs, PNGs and TIFFs are capable of storing textual data to provide more information about the image as well as technical metadata in the image file that details the photo-taking conditions such as camera make/model, if the flash was on, the shutter speed and aperture value, etc. The ImageInfo plugin extracts this metadata and allows Zoom to index this metadata according to its configuration. Although it is most likely that the technical information is present, it is quite common for the informative metadata to be missing from these files.
