Deleting after downloading photos

Question

How come sometimes iPhoto asks if you want to delete after downloading and other times no? Is there somewhere in preferences that is a surefire way of deleting instead of having to trawl through it manually when it doesn't give you the option?
Thanks.

Make sure that all of the years are selected in the source pane. (In the column to the left) click on the triangle next to the word "library" so that you can see a list of years below it. Be sure that all of the boxes are checked (each year, plus "early photos"). As long as they are all checked, you can either leave them visible or click the triangle beside "Library" to conceal them. If you don't have all of the years checked then the word "Library" will have an X by it, and some of your roll options are not available. Once you have done this, the X is removed, and you have the option to create a new film roll or smart album.
Then go to the View menu and choose "Sort Photos" > by Film Roll. Do you see any roll titles in the main viewing area - the big window to the right of the source pane? Even if all your photos are in the same roll, you will see the title of the roll above the thumbnails, and the number of photos in the roll on the right side of the screen across from the roll's title. [Try moving the thumbnail slider all the way to the left to make your photos as small as possible.] As TD said, rolls do not show up in the Source Pane. There you see Albums, Folders, Smart Albums, Books, and Slideshows... but never Film Rolls. Can you find yours?
