Hi,
The Insert Image button is designed for linking to images that are already on the internet. You would just enter the address where the image is located and it would show up in your post.
If you have pictures on your computer that you want to post, you have two options:
1) You can add them to a regular forum post (like this one) by using the Manage Attachments button. When you make a new post, you should have an "Additional Options" section near the bottom of the page on which you write the post. It should contain a button that says "Manage Attachments". Clicking that should open a new window. In the new window, under the "Upload File from your Computer" section at the top, click Browse, select the picture that you want to post, and click Upload. Repeat that for each additional picture, then click "Close this window". Then in your main window (the "Post New Thread" or "Reply to Thread" window), submit the post by clicking "Submit New Thread" or "Submit Reply".
2) Or, you can upload your photos to our Photo Gallery section. You can get there by clicking "Photos" near the top of any page, or just
click here. Then click "Upload Photos" near the top right of the page (or
click here).
Let me know if you have any more questions. Thanks!
