Shapefiles do not support raster files, so I created a geodatabase and made feature classes of the points. I then added a column titled "photos" and added the photo as a raster to the point. I now have several .lyr files with rasters attached to the attribute table and ideally I would like to merge all of these layer files together so the photos (raster files) will all be contained in one .lyr file. I guess I should have merged the point shapefiles first, then made it into a feature class and add the raster files as photos to the merged file and created one .lyr file, but we didnt do it that way and I'm wondering if there is a shortcut to merge the .lyr files instead of attaching the raster files all over again. I am using Arc 10.3.
