It's not in TIFF6, the PageMaker extensions or > TIFF/IT. Was this image generated using Pixel Translations based scanning software? if so then if the strip count is one, then you can find the entire JPEG inside the image at the JFIFOffset position in the file. If the strip count is greater than one, you'll need to reconstruct the jpeg by replacing the restart markers between each strip. I have some code that does all this if you're interested. Rex.
