Hi Tumasgiu, Sorry, for not updating you. Yes, I followed up on your suggestion and Regina, Adrian, and some others assisted me in building PostGIS with a MrSID-enabled GDAL. My Out-DB rasters are in the MrSID format.
This raster file exist on the filesystem and when it is loaded directly into QGIS it displays the image (aerial photo). Also, when the same file is stored in PostGIS as a raster (IN-DB), it can be viewed in QGIS (using the DB Manager tool). However, when I reference the same file as an OUT-DB raster in PostGIS (in this case only the metadata of the raster and the filepath to the raster file is stored), an attempt to view it in QGIS (using the DB Manager tool) results in a black image being displayed instead of the aerial photo.
