Hi is there any plugins out there that will simply give me the ability to share a picture from my gallery on facebook?

Yes, see the extensions section.

I have checked around, and I cant find anything. Could someone point me in the right direction?

Then you did not look right and did not even try our site's search

I did find those plugins. But for me its overkill. All i want is a share button that you find on youtube or in coppermine. One click and your picture is shared.

Facebook provides code for such buttons. Or use addthis.com. In any case you will have to modify the theme used yourself to add that.

look for Facebook Toolkit 2012 at Warriors Forum.com. I'm using it on my site, see it here: Dicas de Presentes
I hope I've helped you and sorry for my english isn't my main language.

This is a little old of a thread that received a bump, but if the OP is still interested in a like button only let me know and I can direct you to docs, maybe split it out for you.
