If you want to open multipage images in read-only mode, you need to call the GifOpenMultiFrameForWrite method for GIF format and the TiffOpenMultiPageForWrite method for TIFF format and set the WriteAccess parameter to false before creating an image.

This method requires the Image Documents component to run.
