We present high-resolution 4-25 micron images of the Galactic Center, obtained with T-ReCS (Thermal Region Camera and Spectrograph) at Gemini South in January 2004. These images are centered approximately on IRS-1 and provide nearly diffraction-limited resolution (~0.5 arcsec) of the central parsec. The optical depth and temperature distributions, determined from basic radiative transfer model fits to the 4-25 micron spectral energy distribution, permit us to examine the details of dust heating by energy sources in the central parsec.
