What you might get initially is an image that "depicts" transparency with a checker background. To get a correct image with transparency you jump-through-hoops and with a bit of luck get it.
Transparency - an alpha mask - does not have to be a chequer pattern, it might show as white or black or checks depending on viewer. Typically a web-browser shows white.
Even Gimp allows you to change it in Edit -> Preferences -> Interface -> Display -> Transparency - Check style.
I use a light setting as (1) I can take a screenshot of that and displayed it "looks" exactly the same in Gimp (2) and also in a viewer (4) The same viewer will show the correct image with transparency as a checker background (3)
Does that make any sense ? Blame the greedy web sites.
Another simple method to check for fake transparency is to move the layer with the Move tool. If the checkerboard moves along, it is fake.
