Welcome to IRV2!! You will find all sorts of info and stories here. It really can be like a big fun party at times. I hope you come back and post many of your stories and questions ... you will always find a helping hand!
As far as posting pics...you first need to have your pictures approved in the album here (must also get approved for posting a picture album) OR have an online place already set up with your photos already there (like PhotoBucket or Webshots)
If you have pics out on the web- then you go to the picture -make sure it is not the thumbnail view- right click on the pic...go down to where it says "properties" . Click on "properties" It will bring up a window that gives you the picture "address" (or URL) . Copy that address - all of it...it may be 2 full lines.
After you copy it then go to where you are posting your message.Just above your message window is a line of "pictures and signs- starting with the Smiley face. The second thing from the right side is a green picture box. Click on the green picture box. Paste your picture "address" into that Image URL line. Click the Ok button. Send your post .. and there will be your picture!
