Do this step after taking care of transparency as explained below. > (2) I would like the background to be transparent (I am using PNG) but > have no clue on how to do that. 0) Alt double-click on the background layer in the layer palette to make it a normal layer 1) use Layer>Mask>Reveal All to create a layer mask. 2) Copy your original signature to the clipboard (ctrl-A, ctrl-C) 3) alt click on the layer mask in the layer palette, and paste the signature to the layer mask. 4) invert the layer mask (ctrl-I) and you're set.
