Note: you can't use the 'quick reply' feature if you want to attach an image. Use the 'Go Advanced" button, which has all the features, or start a new thread, if appropriate.

1. Click "manage attachments" above the "submit" button.
2. Click "browse" , find your file, then click "add this file" ONCE.
3. *Wait* for the image to upload - you'll see the filename appear once it has. This could take a minute or two! Click "all done."
3. If you get the message that your file is too big, it is. You'll have to edit it down and try again.
