Abstract
A method of inserting an image into a container file including reading source data including the image; opening the container file where the image will be stored, the container file comprising one or more records. Each record includes an image file section reserved for storing the image, an image metadata section reserved for storing data about the image, and a record metadata section having a status flag or status mark indicating whether the image file section is empty. The method further includes determining whether the source data is valid to be entered into a record in the one or more records; if the source of data is valid, preparing the record and the image metadata; and writing the record into the container file and marking the status mark of the record as being updated while writing the record into the container file.
