To post a picture to the site.
It needs to live somewhere on the internet.
Here are some examples of hosting that you can use if you do not have a place to put them. http://photobucket.com/ for hosting and http://www.download.com/FastStone-Image ... 24485.html for resizng. Both are free and easy to use.
find the picture on the internet. Then right click it - click on properties.
Then copy the entire address listed (example http://www.site.com/skskskss)
Then go back to the board where you want to post the pix.
click the IMG button right below the topic box - then paste the address that you saved. then click the IMG button again
It should look something like this [IMG] http://www.site.com/skskskss [\IMG] just without the spaces
click preview and it will show if you got the picture posted.
then click submit.
hope that helps
