thanks for the replies, but i think i have been misunderstood. i dont want to merely display the image, i need to have the image georeferenced using control points. if i know that the corners of the image lie in certain x/y locations, how can i register this image so that if i overlay polygon data over they will show in the appropriate position. I also need to know if it is possible to create a dialog in mapbasic to control the act/deact, addition/remove layers. i know i could use radio buttons or checkboxes, but i need the dialog to be dynamic. what if i create 4 radio buttons and the user opens another layer. see? then the dialog would be outdated, and be recreated. is this possible? It would also be better if i could change the order of layers from within, i dont want the user to deal with mapinfos layer control. thank you guys.
