BoostSuite ads run as text ads by default, but upon request we will setup image ads for our paying customers.
If you would like an image ad designed for you we recommend you visit our friends at bannersmall.com and purchase a 300 x 250 pixel ad. They can then send us the finished ad graphic to implement in your advertising campaign.
That said, our customers have achieved better marketing results with text ads than with image ads. This is one of the main reasons we focus on text ads.
