Help with signature?

[Aloha]

I tried practicing making a signature and haven't done one in a good year or so.So this is it basically,because my town is name Twilight after the town in KH2 but the thing is,if I put it in the preview,the background is white,and not transparent,so I'm kind of stumped.I saved the image as jpg.Am I missing something? ; n ; #Photoshopnewbie



See what I mean?
(Well the background shows up transparent on the forums,but when I set it as my siggy in settings,it shows as this big and white box on the outside of the circle)

Try saving as png. If that doesn't work, idk.

Im not sure how to help currently. Can you screencap your layers for me? And for it to be transparent when you save it, you have to save it as PNG

You kept the background layer when you made the signature, correct? If so, that explains the white. You'll have to render the signature itself from the background and then save it as a .png to keep the transparency.
