Hi Emile! Welcome to The Daily Puppy from Oliver & Henry, and their Mum.
We would love to see photos of your puppy. Most of us use Photobucket to upload photos on to the Forum. It's free and very simple to use. It provides an "IMG" code that you simply copy and paste into the body of what you are posting, then click preview before submitting, and your photos will appear. As far as your profile picture is concerned, I'm not very good at that as they have to be a certain size, and I usually have someone help me with that.
Another benefit of Photobucket is that if heaven forbid, something ever happened to you computer, your images will be saved in another location for you to retrieve at any time. You can also use it to attach photos to emails. When selecting the size you wish on Photobucket, select Large, not X-Large as that size will cut off the right hand side of your pictures when posting in here.
We have a Behaviour Section that has some of the most commonly asked questions about puppies as "stickies" at the top of the thread, covering everything from basic Housetraining to Nipping & Biting. You may find some very helpful threads already in existence in there.
