You'll do better with totally fresh content as far as listings are concerned. Think about the amount of market saturation of affiliate content. Multiply it's use by all the affiliates a program has, figure about 1/3 to 1/2 are using those pictures for tgp, and then you won't wonder why you get rejected for "content overused".
The extra bucks you spend on content will make you extra bucks (that is if it's not a model-specific or reality type site that needs specific content that only they can give).
