Ok, I understand now that OJ image layer is actually a vector index file whick contains the footprints of the images as polygons and the path to actual image files as an attribute. Just like Mapserver tileindex files which I am working with every day. Seems to work well, I had a try by adding 8 ecw files into the layer image catologue with the Right click - Image Layer Manager system and now they work together as one seemless layer. But I fear it is not possible to save and reopen this image index file with the project.
