Creating these custom boxes/images

Hi

I want to be able to create something similar to the boxes with images and the title placed on the top as in this example . My theme doesn’t currently allow the placing of sidebars adjacent to boxes but that should be fixed in the next release, however, I would like some ideas about how i could achieve a similar look using a plugin or coding in the HTML content area (note the rollover isn’t required). The theme is platform pro.

Thanks
