    Alright I'm creating a transparent image, however, every time I save my photoshop file as a JPEG, it adds a white background... What's the deal?

    I don't think JPEG supports transparency.

    Reaching your left retina.
    Exactly jpeg does not allow for transparency. PNG is your best option.

    use GIF (which has no alpha transparency, only colorkey) when you need it to work in ie6, otherwise use PNG

    just note that large transparent pngs can cause tremendous slowdown in <IE9

    • PNG supports Alpha Transparency, that is that the image can have different levels of alpha (or opacity) throughout.
    • GIF supports transparency too, but any part of the image can only be either transparent or opaque. There is no gradual shift, no "Alpha" level to adjust. (And transparency eats into 1/256 of your available colors.)
    • JPEG supports neither form of transparency.

    Internet Explorer did not support transparency in PNGs until IE7, I believe that it would show black instead of the page behind the PNG image. It did, however, support PNGs. (Which are still a great way to achieve a non-lossy, high-color image. (even without transparency))

    What do you need it for? You can also get a transparent image with an EPS and a Tif also. It all depends on the application.
