Using the CFCCD imager on CTIO 1.5m telescope, we have obtained optical emission-line images of the majority of supernova remnants (SNRs) in the Large Magellanic Cloud. Most of the SNRs have been observed in the light of Hα, [SII], and [OIII], together with ``continuum" images in one or two off-emission-line bands. These continuum images have been aligned and subtracted from the emission-line images to provide star-subtracted images which allow for study of both fine detail of the filaments and the fainter filaments of the remnants. WCS coordinate solutions have also been calculated for all images based on the USNO-A2 catalog, providing detailed positional information for the remant filaments. This project has been undertaken to provide a database of images for studies of the global emission-line properties of the SNRs in the LMC. The database will also serve as the foundation for further multi-wavelength comparisons with data ranging from radio to X-ray wavelengths. This work was supported by Union College's overseas program, and performed as a part of CTIO's student research programs.
