To add pictures, look at this quote below
Ok so first you are going to need to go to a image sharing website such as tinyurl.com or photobucket. Ill use photobucket as a example since I use this often

Click into photobucket and search up the image you are wanting.

Once you find your image then your screen should look more or less like this. On the right hand side gives you coding so this certain image can be viewable on other websites

from there all you need to do is copy this coding only in the IMG section found on your right hand side of photobucket. After that you need to shuffle back to Feral Heart and go into your profile and click on Forum Profile Edit

After you click that then it will give you options such as "Signature" which is what you want. From there you just input the IMG coding you have gotten and then save it. In a few minutes or so you will have a signature.

Again I do hope this visual representation helps you in some way. It's the basic general form of putting images on feral heart and just a reminder that there is a limit size to what signature you are able to put in.
Good luck
Your welcome and good luck. :3
I'll lock this since you already said that it's solved but I just wanted to mention that you can also use Tinypic.com. Photobucket is a great site like Thrillex mentioned above I use it myself most of the time but you'll need an account. If you're ever having lazy days or just don't want to make or sign into an account you can use this method too:
Adding pictures to your posts.

Go to Tinypic.com. This is the home page. You do not need an account, but you can create one if you'd like.
Click 'Browse'. Pick the photo you want and click it. You can choose what size you want it as well.

The codes are located in the light yellow rectangles. Copy the code under 'IMG Code for Forums & Message Boards'. Paste the code in your post.
