Have you figured out the posting pics part yet? If not PM me
For the untame part.... PATIENCE (Something I have 0 of, but it does work)
Also if I may give some advice....
Try wrapping him in a blankie/towel like a burrito, maybe he will feel more secure till he warms up to you again and then also
If you pick him up and he squirms, don't put him back, pick him up again, talk softly and when he stops squirming hold him a few seconds longer and let him walk off your hand.
You can then also offer a little treat/reward.
If you let him go each time he squirms, he will associate it with "If I squirm, I get put down/left alone" where the other way he will learn "If I squirm, nothing happens, If I stop I get praised/treated and put back, they wont hurt me"
