    Change White to Transparent

    I have a png file in grayscale. I would like to change all of the whitish areas to transparent, allowing me to overlay it on another image. Any ideas?

    T.I.A.
    Regards

    I have a general idea of how I might do it in Photoshop Elements: open image, convert it to a layer, use the magic wand to select white with the appropriate degree of similarity for close shades, then delete, then save with transparency. This leads to sharper or fuzzier edges depending on your wand settings (I think).

    The method for doing this varies with the software you plan to use to perform the etching. A magic wand tool can work well but you might also specify a particular colour as transparent when you are saving the png. Another alternative is to use a masking tool which might be available in your software.

    Thank you both

    Thank you Jefferson and Andrew

    In another forum, Hans V offered me the following advice which nicely did the trick.
    IrfanView will let you choose a color to become transparent when saving a .png,
