You can try and post the photo under Pictures and choose the relevant parish, so more people can see it. Also, our Swedish National Archive plan to make the digital service "SVAR" free to use. I think that it will be free for people outside Sweden too. If not you can pay for SVAR or ArkivDIgital. If you are going to take your genealogical research seriously you will probably need one of them or at least Ancestry with Swedish Archives. Simplified I would say that you first should go to the birth records that you know for sure, check who the parents are and were they lived, go to the household records and see their birth places and dates. Follow the family forward in time as ong as you can and then go back and check up the parents birth records and so on.
