The present invention relates to a system and methodology facilitating storage, access, and version control of PLC-based images. An object is provided that mediates access between a database server and an application that desires access to such images. Before access can be achieved, a login and authentication process for a user desiring access to the image database is performed, wherein users who are successfully authenticated can then save, retrieve, and affect changes to the images in a substantially secure manner while enforcing protection against invalid or improper changes to the images. The object is adapted to store the images as a complete or compiled version of the elements required to operate a PLC program. Since PLC images are different than standard data types that are typically stored, a check-sum procedure is performed on the image to determine if changes are made. If changes are made, a metadata file that is associated with the image can log relevant change information and bump an associated revision information for the image thus facilitating automated an orderly control over who, how, when, and where such revisions can be made.
