I try to something like this dim img1 as RasterImage ' multipage tiff file dim img2 as RasterImage ' multipage tiff file ' loading 2 images myViewer.Image = img1 myViewer.Image = img2 After that I try to access to img1 but I get an error message: "No pages in this image". If I debug img1 the pageCount and some other values are ok. But most values are "Reference not found!". How can I "unload" img1 from the RasterImageViewer so that I can change the image source for the viewer? Thanks Riggson    Report
