Help me post a pic, please

I tried to post a picture of a very cool LR hitchhiker in my last post and I managed to finally get a photo within my text. But, it is HUGE. I need some more help I guess. Could anyone give me some guidance?
Okay I visited my post and now its not showing the pic at all. I set up an account with to host pics so that I could do this. Aaaarrrggghhhh.. Have mercy on me and help:(
