Theres a thread that explains how to post pictures in the strategy section Id make a link thing for it but im to lazy to learn how atm
You need to download an app called 'photobucket' and upload pics onto there. Once uploaded, you go onto the pic and press the 'i' icon in the bottom right corner. Then copy the bottom img code. Paste onto a thread. You will however perhaps need another photo resizing app first to make sure the pic is sized correctly before uploading on to photobucket. I usually use around the 200 x 300 mark and it comes out ok.
