what is the mistake in this sentence

[Nader75]

what is the mistake in this sentence and I must to clear and add to it

how mush is the size of somthing....
have you pic for you

[Tdol]

1- mush - should be 'much
But, I think the sentence would be better like this:
How big is ...? or What size is...?
2- I'm not sure, but do you mean this:
Have you got a picture of youself?
You can use 'pic' as a shortened form of 'picture'.
