Of course! My pics are open to anyone, just say the word and I'll slap your name on one of em.
Here's how you get one into your sig:
Go to 'My Profile'. Then click 'Update Profile', and scroll down to the text box for your sig. Let's say you want a pic called 'Magic', and the link to Magic is in the site
www.Magicpic.com. Let's also say that the Magic file is a jpg file.
You would write this in the text box:
