The Foxer

The 25 pictures in a cluster foxer are arranged in 5 discretely/discreetly themed clusters. Pictures in a particular cluster must be cardinally contiguous to be valid. For example, A1, B1, C1, D1, D2 is a possible cluster, unlike A2, B2, C2, D2, E3. To fully defox today’s enlargeable puzzle identify the themes and constituent images of all five clusters.
