Swapping images that have image maps

Question

Using RoboHelp 8, I'm embedding images and adding half a dozen image map shapes with links to distant topics in my help project. Every time I modify an image, it seems I have to swap it out with the image I put in previously (unlike, say, in InDesign, where you can create an automatically updating link to an image). And every time I delete the image, the maps disappear and need to be re-created.
1. Is there a way to link images in RoboHelp to avoid the manual delete and replacement?
2. Is there a way to store image maps so they needn't be re-created every time their underlying image is replaced?
Thanks much.

Rick,
Sorry, some weirdness happened and my last post got posted before I finished.
Here's a more detailed scenario.
I open Microsoft Visio and create SampleImage. I save it as a gif to my RoboDrawings folder. Now, in the RoboDrawings folder, there is an image called SampleImage.gif.
I quit Microsoft Visio.
I open RoboHelp and create a project in which a topic is called SampleTopic.
I insert an image, go to the RoboDrawings folder and select SampleImage.gif.
I create a few image maps linking to various other topics.
I save everything, generate html help and close down RoboHelp.
Now I open Microsoft Visio again, open SampleImage and change it drastically without resizing anything.
I save my Visio drawing under the same name, perform a Save As and go to the RoboDrawings folder to save the image as SampleImage.gif. I get a message warning me a file of the same name exists, and I choose to overwrite it, eliminating the old file.
I shut down Visio.
I open RoboHelp, view SampleTopic and the old image is there with image maps in place. I generate html help again, and the old image is still there with its maps in place.
Without deleting the old image in the SampleTopic and manually inserting the new one (same name, though), how do I get RoboHelp to acknowledge that the image has been updated?
