We present mapping, profiles and photometry for 24 planetary nebulae (PNe)\ndetected in the GLIMPSE 3D mid-infrared (MIR) survey of the Galactic plane. The\nPNe show many of the properties observed in previous studies of these sources,\nincluding evidence for longer wave emission from outside of the ionised zones,\na likely consequence of emission from polycyclic aromatic hydrocarbons (PAHs)\nwithin the nebular photo-dissociation regimes (PDRs). We also note variations\nin 5.8/4.5 and 8.0/4.5 microns flux ratios with distance from the nuclei;\npresent evidence for enhanced MIR emission in the halos of the sources; and\nnote evidence for variations in colour with nebular evolution.\n
