Oh, come on! Help the DUMMY!!!!!!

I'm pretty much a dummy when it comes to computers, but there's almost nothing i can't build as a mechanic. So, somewhere in between there's gotta be SOMEONE out there that can give me steps from the very beginning to the end how to post a picture. I've got projects to share, stuff to ask advice (like this), and stuff to sell. So, COME ON!!!!!!!!!!!!! Isn't there an idiot like me that had his (or her) hand held til you got it right and can now hold (not literally) my hand. Stand up idiots and be proud!!!
