Hello Jayvin, welcome!

A scanner works best for stamps to show the details. To see an expensive stamp you need to scan at 200-600 dpi. A camera will not do it justice or show details enough unless you are a professional photographer.
Then you need to crop the photos down to just the stamp(s).
The reduce the image to posting size 100KB on thois forum.
OR, use a photo josting service site such as Flickr, photobucket, imageshack to upload to and then just put a link here on the gorum.
Remember that not everyone has high speed connections. Use the photo resizing tool (click Reply To Topic link above right).
Read the rules of the forum by clicking the Rules button top right. You need a certain number of posts and time here to buy/sell/trade.
To show and share and comment and question is what we all do. Ask away, comment away.
Have you collected stamps before now? Are you thinking of collecting? To appreciate what you have while you have it is a great thing.
