one issue is see is that you are using 4 recordsets to pull the featured images, why not just use one and add an OR condition to the where clause:
WHERE FeatureCategoryType = 'Homepage1' OR FeatureCategoryType = 'Homepage2' OR FeatureCategoryType = 'Homepage3' OR FeatureCategoryType = 'Homepage4'
also in the feature table, try adding an index to the feature.FeatureProductID column and the FeatureCategoryType column, that may help speed up the queries.
