Thank you @angelica2017 I'm really glad you think my sun glasses look as cool as in MIB! \o/

Yeah you can fully edit your posts text and Images after post it, you just have to click in edit, then erase the link with the old image than post the link to the new one.

I'm I think it is just cool to help those who are starting now, I've been in your position like a month ago, and I would have loved if in my first posts someone has offered some useful info and offered him/her self to answer questions.
so I'm just doing what wanted others had done to me ^^
and also it os good for everyone if new users get use to and like steemit as fast as possible so that way they will spread their success history and will inspire new users to keep coming which makes steemit greater and better to everyone !
