Hi,
I didn't get lost if you were worried:)

I'm writing a post about how to make posts pretty which hopefully will answer all your questions.

I've figured that it would take the same amount of time to write it here for you as I can make a post and everyone benefits:)
I'm asking a little bit of patience because the topic is complex and I'm also a learner myself. I think it will be online in a few hours.

I have not used photobucket before but it seems that you have to register there. If you don't want to you can use imgur.com or tinypic.com or imgsafe.org. These are all free, with no registration required.
