Alot of people, including me, have no clue on how to put pictures in your siggie so I figured it out so I would like to share it with the rest of you who don't know how to. Here's the steps:
Step #1. Go to the picture you want to put in your siggie.
Step#2. Right Click over it and click on Save Picture As... and click Save
Step #3. Go to tinypic.com
Step #4. Go to where it says " Upload Images and Videos"
Step #5. Go to where it says " File" and click on Browse.
Step #6. Click on the picture you want.
Step #7. Click on Upload Now!!
Step #8. Once it uploads it will show you different codes you can use but you want to use " IMG Codes For Forums & Message Boards" and click on it to copy the code.
Step #9. Go to your profile and go to your Signature and paste the code. Make sure there are no spaces between the codes.
Step #10. Click Save and Wala You have a picture in your siggie!!!
I Hope This Helps!!!
