    I have some old TIFF files that appear blank when I open them in Preview, GIMP, Safari, etc. The only programs that display them properly are GraphicConverter and Photoshop Elements (Windows). I have looked on the web for an answer, but I have not found anything that would explain this.

    Do they have layers or any extra "stuff" in them? Perhaps CMYK vs. RGB?

    They are RGB; I haven't been able to find anything extra (layers, alpha channel, etc.)

    Another stab: are they saved with any sort of compression?

    No. (According to GraphicConverter, compression is 1:1.)

    I just found something; GC's ExifTool reports "Extra Samples: Unassociated Alpha" for the affected TIFF files. Could this be the cause?

    Good question! I have no idea, really.
