Want to view images in sequence and delete I have downloaded photos to an iMac from camera into folders, not iPhoto.  I want to view the images on full screen in sequence and delete images as I go through them. I have come from Windows where there is a program that does that, but cannot find similar in the iMac.
I would (in Finder):

1) Switch to list view &#x2318;+2

2) Select the first picture in the list

3) hit space to activate Quick Look

4) if you want to delete the photo you are viewing hit &#x2318;+delete

5) otherwise hit the down arrow to go to the next picture
