There are many picture hosting sites that you can use - A good free one is http://tinypic.com/
You can either just upload pics or register for a free account to save your pics for long term use
Once uploaded it will give you the codes to use in a different ways - eg forums email webpages and so on
Just paste the IMG Code for Forums & Message Boards - remember you might want to use the option when you upload your pic to resize the pic to message board size else the pic might appear huge on the forum - However if its something with text that needs to be seen clearly you can upload it at full size and the put the HIDE tag around the IMG code - This will hide the picture in the spoiler on the post so people will need to click the spoiler to see the pic - tus will save loading time and keep the thread looking cleaner from really large pics in posts
