Access Master-Detail Image Form (External Files) A common question in Access is how to overcome the limitations of "Continuous Forms" when using images. The Paging sample presents a solution for displaying multiple images on a form; this sample builds on the Paging technique by incorporating it into a one-to-many relationship, allowing a variable (and unlimited) number of images or photos for each master record.
A subform displays the images for the current record using a fixed grid of DBPix image controls, with Prev/Next buttons to navigate through additional "Pages" of images. To add or edit images the subform is dynamically switched to a standard form in "Single Form" view.
This sample stores the images as external files (i.e. "linked"). A version with images stored in the database (i.e. "embedded") is available here.

Technical Overview
This sample takes the 'Paging' approach and combines it with a one-to-many relationship and subforms to produce an application with a 'Main Photo' and 'Additional Photos' structure. The multi-view form of the Paging sample is used in a subform to display the 'Additional Photos' for an item, supporting a variable and unlimited number of additional photos for each item. To edit the additional photos the 'Multi View' subform is switched for a different one, which is based on regular bound controls in a single form view.
