    Does this only happen with Yahoo Mail site (which I don't use)?

    Try this, go to <>, and
    if (like me) you don't have a TIFF plugin installed and working, I
    click the "viewed standalone" link and be presented with a "Open
    <file>" window, and I leave "Open with <my default viewer for TIFF>"
    selected and do *not* check the 'do this automatically...'.

    The "dscf1665.tiff" file is (temporarily) saved to (on my OS)
    "C:\Users\username>\AppData\Local\Temp". When the file has downloaded
    and saved my image viewer launches and opens the file for viewing.

    The file should also be listed in the Downloads (Tools > Downloads).

    Why does it have a .part file extension?
    The .part file extension usually means an incomplete file.

    If I download any file from a web site and save it to any folder,
    while the file is downloading, it's incomplete and the file has a
    ..part file extension.

    Wouldn't the [8character_string].jpg.part be saved to the temp folder
    with that same name and a .part file extension?

    As no app should be associated with .part, did/do you check
    "[x] Do this automatically for files like this from now on."?
