So your the one with lovely Shina! I'm soooo glad you decided to join! My name is Julie and I am owned by 2 dogs, Daisy a golden retriever, and Molly a Sable and White Rough Collie. (both in signature) I also have a 7 month old Pied Cockatiel named Piper, a hamster named Neko, 2 cats named Angel and Dillian, and 6 desert tortoises.
Okay, in order to get a picture to use as your signature, you must upload the image to a picture uploader, such as www.imagestation.com. Save the picture you want to use in a folder, or on the desktop, so you will be able to find it. After that, click a button on imagestation that says "Upload Images". It should take you to a page with 3 bars, and a button that says "Browse". Click browse, and find the picture that you would like to use. Then, click "Upload Images". It takes a few minues to upload. After it's done uploading, it should take you back to the picture. When it does, click "Go to Storage Bin". There you will find your picture. After that, click on the picture, (a new window should open up) and right click on it and click "Properties". What you want is the address (URL) Highlight it and Copy it ( Ctrl + C). Then, come back to Pet Talk and click "User CP", at the top, and then "Edit Profile". Paste in the URL, where there's a space for the signature. After you do that, at the very beggining, put [img], then at the very end of the address put [img]. FINNALY, after that you can click "Update Profile", and the picture should show up.

If you have any questions, let me know.
