JSI Tip 5278. When you click a link to a Tagged Image File Format (TIF and TIFF) image in Internet Explorer 6, you are always prompted to open the file directly or save the file?

If you have cleared the Always ask before opening this type of file check box, you are always prompted when you use a link to a Tagged Image File Format image?

Use Regedit to view HKEY_CLASSES_ROOT.tif(default) and HKEY_CLASSES_ROOT.tiff(default). If either value is TIFImage.Document, set them both to Imaging.Document.

You could Merge the following .reg file:

REGEDIT4[HKEY_CLASSES_ROOT.tif]@="Imaging.Document"[HKEY_CLASSES_ROOT.tiff]@="Imaging.Document"
