Need to add 4 add'l image boxes to homepage. The default 4 is not enough.

HELP! I am on a deadline and this is driving me crazy. WordPress Discover theme, I would like to add 4 additional image box headers, images, text and link lines. I was able to adjust the options.php file to add these add’l components, and changed the element.php file to reflect 8 columns. When I view the site I get the first row of images, but the second row is ragged and stacked all wrong. What aren’t I doing or what am I doing word. Again this is for the Discover theme.
