I'm taking a look at the new V7 Image[] command, and I'm left a bit confused. 1. Is Image[] any different than Graphics[Raster[]] that I'm more accustomed to? 2. If not, what was the point of introducing Image[]? Was it any effort to provide a more streamlined set of commands all revolving around Image[], e.g., ImageRotate[], etc.? 3. Image[] somehow upsets my unified view of Mathematica. That is, I like to try to "think" like Mathematica, and so I understand that all commands like Plot[], ListPlot[], etc., reduce to a Graphics[] object in FullForm[]. Similarly, I can build my own type of plotting function with Graphics[]. Most importantly, I can combine many different types of objects into a single Graphics[]. Am I correct that Image[] represents then a completely new display object? If so, is there a way, for example, to have an Image[] and then draw across it with an Epilog rule like you can do with Graphics[]? It seems a major setback if Image[] and Graphics[] cannot be readily mixed. Anyone out there to make the case that Image[] represents an important new capability? I see it as a little worse than the usual "new command that does same thing old stuff did" because it seems to lose the capability to mix Graphics[] and Image[]. Please inform me if I'm completely off base. As I said, I'm just digging into Image[] now for the first time, and I'm a bit confused about possible merits---please do inform!
