Adding a signature to a picture

Hey im want to know how to put a signature on a picture...to make it look like someone actually wrote onto it.

There are several ways to do this.

Use a handwriting or script style of font.

Scan a signature into your computer and then use that.

Use a pen and graphic tablet to make a signature.

Once you have a digitised signature, you can easily place it onto another image. If have lots of images to do, you use an action to batch it onto many images.

I want a real signiture on their. If I scan a signature and paste it onto the photo, wont their by white space around it?

You can save a graphic of a signature as a GIF or PNG file with a transparent background.
