It’s probably a lot easier than you expect http://codex.wordpress.org/Embeds
wow – that was too easy! thanks for the help. Videos are up and running … and it looks like I knew what I was doing.
Okay, one more question then (since the first was so easy)
When I add images to my post, I assumed that the layout was WYSIWYG, but when I try to place images side by side, things get messed up or complicated. When I preview the post, they’re not level or one seems to be overlapping the other so I just end up stacking them.
Is that an easy fix too?
thanks.
Your supplementary question has nothing to do with YouTube embedding so you should really start a new thread – with a link to an affected page so people can see the issue.
