If you are using the Bing Maps Silverlight Control for WP7, there are APIs for want you want to achieve.

The Map class for example provides methods LocationToViewportPoint and ViewportPointToLocation for converting coordinates.

There is also the class MercatorUtility which provides helpful methods like LocationToLogicalPoint and LogicalPointToLocation.

However, depending on what you mean with custom map image, nobody except you would possibly know how it maps to view coordinates.
