There are a couple ways of posting pictures on this forum.
1. The quickest and easiest is to open a Photobucket.com account and follow the directions to upload your picture to that web site then click on the picture and you'll see a list of "Image Links" on the page. Go to IMG Code and click on the code and it will copy then go to your post, right click then click on "Paste". If you then Preview or Submit you should be able to see the image in your post.
2. You can upload your image directly to the forum by clicking on the "Insert Image" Icon then click on the location of your image, your computer or online and click "Select File" once you have selected the file click on "Upload" to bring it to your post.
3. Almost any picture on the web can be shown on your post by right clicking on the picture then picking "Copy Image Location" on the drop down menu the paste the address in your post. You also need to put [img] before the image address and [/img] after the address.
I know these methods sound complicated but once you do it a few times it becomes a lot easier. If you have any questions or problems let me know in the "Just Talk" forum.
