heids82 - as others have said, to link to any galleries here, just copy-paste the address from your browser's address bar into the forum post.
For example, here is one:
http://livinginlimericks.wordpress.com/2012/12/13/moments-in-cork/
That gallery looks quite lovely to me! Is there something about it that doesn't look like what you'd expect? As justjennifer said, the reason the gallery isn't taking up the full width of the page is that the Twenty Ten theme displays posts in a two-column layout, with the right column currently containing the search box, Archives, and Meta.
If you want your gallery to take up the full width of the page you could look for a different a theme that displays posts in a full-width layout, instead of a two-column layout.
justjennifer - I've moved the newer post you referenced into the Themes forum. (The older one is already closed because of its age.)
