elementary help re iphoto

I don't know what I did to cause this, some swoop of my mouse:
I now see, after I did some enhancing and rotating, some pretty pleasant photos of Katy dog.

I don't know how to delete (there are the odd duds). I don't know how to post them yet on a2k.

Bear with me, iphoto is different from when I last paid attention.


I'm guessing - I pick a photo and add it to photobucket or other?

I also don't know how to somehow log this (in a book? or one of many other choices?)

I don't know how to shut it down without losing it.

Which fits, as I didn't know how to get here. I'm not closing the screen in the mean time.
