Publishing materials on a forum could get a bit tricky, and this tutorial is intended to show you how to insert photos and videos into you post.
We'll start from the videos, because that is the easy part:
VideosThis forum allows you to post videos from Youtube and Vimeo using the

and

buttons in the post editor.
To publish a video, simply copy the link from Youtube/Vimeo and paste it into the editor. Then, highlight the link and click the

or

button. You're done!
Photos1. If you are posting a photo from another website, all you have to do is copy and paste the link to that photo into the editor. Then, highlight the link and click the

button in the post editor.
2. If you want to upload a photo, click on "Attachments and other options" below the editor, under "Attach" click "Browse..." and select the photo you wish to upload. Each photo you upload will appear under the text of your post as thumbnails. By clicking on the thumbnails, the photos will expand to their full size.
If you would like the photos to appear inside your post, you can do that in the following way:
First, repeat the procedure under point 2 above.
Next, click the "Post" button.
Right click on the thumbnail of the photo and select "Copy Link Location" in Firefox or "Copy" in Internet Explorer.
Select "Modify"in the upper right corner of the post.
Go to the location in your post where you want the photo to appear and paste it there.
Click "Save Settings" in the bottom right corner to save your changes.
You're done!
