Easy way to copy images to Gallery

I have a feeling I already know the answer to this question, but is there an easy/quick & dirty way to add images that I have posted in threads to my gallery? Something like a click on the image in the thread and then add it to my gallery.

I know I can save a link, and then upload... or upload again from my computer... but why have it loaded two times on the site? Just a curious mind wants to know. Ha!

If you upload to the gallery first you can place it in a thread from there using the My Photos button at the bottom of the reply box,hope this helps.

Mike, thanks. That I realize, but I didn't at first. This is why I am looking for a way to go the other direction. Ha!
