How do i develop the image after i have exposed a photo paper ?

Do I understand you right? You have exposed a photographic paper through, say, a pinhole camera and now want to develop the image? You are going to need some chemicals from your camera store. The first is called, appropriately enough, developer (dektol is good), then fixative (sodium thiosulfate) and finallly a bath in surfactant. If you can get a red light bulb most papers will allow you to work in red light rather than total darkness. This allows for one of photography's most magic moments; watching the image appear on the paper in the developer. Once the image is where you want it you wash the paper in plain water to get the developer off before placing it in the fix to stop the developing process from continuing. (if you don't do this the entire page will eventually turn black.) Once fixed, wash the image in surfactant solution before hanging it up to dry. The surfactant allows the paper to dry without water spots.
Your next question may be, "Where do I get these chemicals?" The tough one will be developer. If you can't find a source in India, I found one here in the States (Porters) They have developers D76 and Dektol, both of which are very good. Sodium Thiosulfate should be available through a chemical supply house and if you can't find surfactant use a tiny drop of dish soap. Have fun...I miss those days.

i miss those days of chemical darkrooms.
you have to have a darkroom, trays to put your chemicals. as leeR said, you'll need a developer, dektol, a brand of kodak, a fixer, and if you wish, you can add a stop bath in between developer and fixer which is a mixture of water and few drops of acetic acid to stop the development process and to preserve your fixing bath. hopefully you used a photographic paper which is orthochromatic, which is not sensitive to red and/or red light. there are some papers that are 'panchomatic' or sensitive to all colors so you cannot use a safelight. most papers require a 2 minute development to attain the best contrast. mix the developer as instructed in the can to make a stock solution. use 1 part stock solution to 2 parts water. the fixer is used full strength.
after fixing, wash thoroughly in running water or in order to save water, you can also use a kodak product called de-hypo to remove the fixer specially if you are using fibre based paper.

Well, the main problem with my camera presently seems to be that i have not got a good rigid light tight box. Hopefully, i can get a good image before 26th april- world pin hole photography day.
