tutubi, If you use potlatch, no easy way. Sorry.
For merkaartor and JOSM, you can rectify the image using an online map rectifier Map Warper beta: http://warper.geothings.net/ After the rectification, you can now use the image as a WMS. One warning when capturing aerial images: "anything below about 70° to the vertical isn't that useful. 45° pictures make nice panoramas but aren't good for warping.
