Also, if you want to gain some of your stoage back, do this.... Options, NetworkHardDrive, You will there see all the Images that have been posted into your group... Go back to your oldest Post, and you can delete some.. Everytime you delete one, the page will come back to the beginning, which will be your most recent post in your group..So watch it...After you delete 1 and the page comes back, make sure you go back to the older post again before deleteing more... I found this just by looking around....
The Forum needs to be "Diamond" in order for members to be able to upload images into a message from their computer. If you have your own Forum, you can read about upgrading to Diamond Status here.
If not, you can upload images using other methods. Please read the thread here for details.
