Problems with sig

[OldReliable]

I made my own little sig but the picture is really small. How can I blow this up to full size?

I dont understand exactly what do you want.
If you want to make your sig bigger: "image" - "Image Size" (photoshop)

But if your sig was upload and then became smaller, you can change your Image Hosting (or change some options in your hosting)

My sig wont fill up the area. Theres white all around it and I cant get it to work.
