Next, to add a smiley..Just simply click 'Reply' In bottom of page..Above 'Quick Reply' And above everything..You'll see the smiley faces. :D
Lastly, the pictures..I would be a example from Feareh^^
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
