    I'll hazard a guess that the file in question has PNG transparency
    settings that Explorer recognises and many imaging apps do not.

    Be easier to comment after looking at the actual small file.

    Maybe it has to do with how you configured Windows to show (or not show)
    background colors for icons. Remember that what you see on the desktop
    is being presented by Windows Explorer. The explorer.exe process is the
    desktop manager and why killing all instances of it results in losing
    the desktop.

    The option is badly worded. It appears it merely has Windows Explorer
    ignore whatever background color is specified in the icon image file and
    instead use the background color configured for Windows Explorer.

    See if toggling this lets you see the background rather than having
    Windows Explorer ignore it.

  4. Thanks Martin, I think you're right. I was just about to post this
    follow-up:

    I think I'm onto something. It must somehow be due to the original
    file being an animated GIF, like this one:
    https://dl.dropboxusercontent.com/u/4019461/OriginalAnimatedGIF.gif

    I wanted a single image and think I obtained it either via Animation
    Shop or PSP8.

    Perhaps that somehow breaks PSP8's display procedure (No checkerboard;
    and on a Background, which is not supposed to contain any
    transparency.)

    And here's the example PNG you requested:

    Drop shadows are not the same as transparent color for
    icons. The transoarent color should always be not showing
    if the icon is made correctly. And PNG is not the same as
    ICO. I'm guessing it's just that PSP8 is too old. Full support
    for PNG is relatively recent.

    PSP9 doesn't deal correctly with this example's transparency, either.

  8. Thanks Nil. Of those three I have only the excellent IrfanView.

    I was getting the same display as in PSP8 but prompted by your post I
    now see that this setting was not enabled:

    https://dl.dropboxusercontent.com/u/4019461/IrfanView-TransparencySetting.jpg

    Having done so, I see the transparency.

    Do you have that permanently set? Do you use the default grey
    background colour?

    --------------------

    I'm now sure that explanation I ventured up-thread is correct.I've
    only recently returned to this task after a longish gap so I'm a bit
    vague, sorry. But I reckon I must have made that original PNG from the
    animated GIF by opening it in PSP8 and saving it. I tried that again
    yesterday and see the message:
    "This is an animated GIF file. Only the first page will be opened and
    saving over this file will result in loss of information."

    I went ahead anyway, as I assumed I could then remove the black!
