Questions from a newbie

Hello , I've just joined steemit and I'm feeling a tad lacking in knowledge, I've looked at dozens of youtube videos (thank you for those) but I'm missing the info on how to post pictures into posts, is there something I'm not seeing? I really want to do this right, I'm not exactly computer friendly, is there a tutorial specific to that kind of thing someone could point me to? Apoligies for being helpless.
