I wouldnt use sponsor content at all these days, its all over-saturated and i know for a fact you have much better content than a lot of these programs do to use.. Just reduce the size/quality of the images you already own and use those babe

The added benefit is that you can then use whatever sponsor you want, on whatever page you want, without the sponsor dictating to you where they have to be linked from on YOUR site
