But without a bit more detail that's all I could say.  

So in oligo there is an image method, but it seems to work (dispatch)
fine for me after installing oligo.  For example:

> ff = new("FeatureSet")
> image(ff)
Error in if (tolower(manufacturer(x)) == "affymetrix") { : 
        argument is of length zero
