To post pictures on this board first download to a picture host on the net(alot of us here use photobucket and it is free).
When you are ready to post a picture on the board just go to photobucket and highlite the HTML tag under the picture you want to post(it is the middle tag). Right click the HTML tag(which should be highlighted)and click on copy.
Now go to Mastiff Guardian and type your post.When you get to the place that you want to insert your picture click on the place you want your picture to appear and then press your Control button down on your keyboard and while holding it down also hit the V key at the same time.
Your picture should now be in your post!
Please remember to size pictures appropriately so they do not come out HUGE.
You can preview them at bottom of your post before posting just to make sure that it worked and to check size of picture.
