Image Catalog
This extension allows the user to view multiple images from one layer and view them quickly and efficiently. An image catalog is a grouping of any number of images into a table. The table contains links to the file location and reference location. You add this "table" into a view as an image theme. This allows you to 'virtually mosaic' the images.
All the images in a catalog must be the same format.
Download the file here (PC users
right click to save).
Add the .avx file to the extensions folder. Open the Extensions menu and
activate Image Catalog. This will add a button to the View toolbar - 
. Clicking on the Image Catalog
button pulls up a menu to select the files to add to the catalog. After
selecting the images, the image catalog is created in the same directory and added to the view. The Image
Catalog allows the user to edit the stretch of the images in
the catalog, but the edits will be applied to all the images in the
catalog.
