We accept four differnet banner sizes as seen below. We may be able to accommodate other sizes upon request. Contact us for more information. 

We accept advertisements in many differtent file formats. We prefer .gif, .jpg and .png. We can also accept Flash and Shockwave formats, but due to conflicts with our coding, these advertisements can not be displayed in the top position. File sizes need to be less than 75 kilobytes in size and be web ready.
