WPG2 and showing titles makes thumbnails 1 per line

I need some help customizing the CSS for WPG2 images. I like to show more than one image per line, but when I choose to have titles displayed with the image all the images switch to one per line. I think it is the <h2> tag that goes around the title.

Does anyone have a suggestion to get the <h2> to not force a new line?
