When you upload an attachment it is already given a name and location. But if you just allow the forum software to leave the image in the "attachment box" at the end of your post you'll never know what it is. Instead, after uploading the image click on the attachment icon again and then click the file you uploaded. This will insert the image into your post. From now on you can copy and paste the image in a different post and it should show up. Alternatively you can right click the image and select properties, then copy the URL. Next simply use the insert image icon and paste the URL. So, this image below is an attachment. It is posted within the post and the URL is http://www.lawnsite.com/attachment.php?attachmentid=141703&d=1238179865. Now I can post it anywhere if I so choose.
