Help with coding

Hey guys, i've been trying to make a thread to rent my max main, but whenever i try and increase font a little in size it always goes to a huge size and i cant change it back. Also how do i make the embedded image smaller?

here's the thread http://www.sythe.org/other-services/1878784-inlovewithbtc-s-max-main-rental-cheapest-1m-hr.html

And here's the current coding, cheers:

[zize=12]Hey guys, i've decided to start renting out my max main for 1m/hour including a 2.5m deposit if I do not deem you trusted enough that you will get back at the end.

Account comes with tentacle whip and dds.

Please contact me below or add me on skype if interested, thanks![/zize]
