This question came up in another thread so I thought it could be useful if you ever want to redisplay an uploaded image in another thread.
This will prevent you from eating into your upload quota when re-displaying previously uploaded images in other threads.
You can upload full resolution images into another thread without re-uploading them by using the BBcode "url" and "img" tags.
The image below is my image originally uploaded in my Huggins Lookout Thread.
Clicking the image below will display the full size image.

Copy/paste the above BBcode into the new thread's post and use the url to your full size image from the originally uploaded image.
