IT dilemmas

Can anyone point me in the correct direction for some simple Blog tutorials? I have seen people post pictures into comments forms but was unable to work out how to do this when I wanted to reply to a dilemma of B from B is Building a House.

I need assistance with referencing pictures too. How do you put it under each picture in tiny print?

I'll just have to slightly modify my mantra till I get it all worked out! (The pic above is perfect but that 'or' should read 'and'!)
