I saw someone's picture is their signature is bigger than 300x70

How to make it bigger?

Maybe the size is determined by the size of the image you uploaded. You seem to have a number of images in your signature, which could be limiting the size of your signature image. Instead of uploading a number of images to your signature, maybe your other option would be to create an album and upload your images to the album for people to view.
