Kerry,
I liked your suggestion of inserting a bmp file as an ole object, and then making a slide file. The resolution was great for the ole object, but the vslide command doesn’t see the object. I tried the “Insert / Raster Image” approach with a bmp file. The resolution was fuzzy. It could make a slide with the mslide command, and view it with the vslide command. The result was poor, to say the least, as AutoCAD converts it into its own 255 color spectrum. The main problem with slides and dcl height and width considerations is that you have to adjust your AutoCAD screen size to the proportion of what you need to see in the dcl image tile. You may need to dock extra vertical or horizontal tool-bars, to re-size the screen size closer to what you need for an mslide shot, but it can work.
