OK but to add to Qimage's talents, let's say that the auto crop was a bit off on centering the subject you want. After all, it doesn't really know whether if cut off anything that you wanted to keep.

Go into the PAGE editor,click the cropping tab, and using the mouse, slide the small image around a bit to suit the position you need.
See attached screen snaps, and then the video below.

It indicates that there is room to move the image in that plane; horizontal/vertical.
If you use the zoom bar, you will have 4 red bars indicating that you have squeezed the image and have room to slide in any of the 4 directions.

Now if you are ready to really get confused like I am, here's another crop tool which has recently been added.
Right click on the large live image center of screen and select the sixth item down. Guess what; a cropping tool.
Use this tool if you are more comfortable sliding the "FRAME" around the image, rather than sliding the image around in the frame.
It opens with the aspect ration of the image, and holds that as you adjust the crop area. You can enlarge or shrink, but the aspect ratio holds.
This is excellent for making sure you get the size print you want, remembering that crop scissor on with an 8 x 10 print size selected will lock that ratio as the aspect ratio, and as you drag a corner, it will hold as 5:4.

Have fun

Is that you Fred?

Yes, but Jeffie, The attachment to this post is Marilyn...
The one of us on the bench is both, BUT, what year?
The one on that balcony was taken in Germany in 1955.
I am not sure of the bench shot as to date.
Anyway, (need Terry, he is an engineer) converting from metric.... that is about 63 years ago.

PS When we had a meal with someone, we actually spoke to them across the table, looking them in the eye.

Some thinking stuff.
You can change the aspect ratio by changing the print size (4 x 6 print is 3:2) and an 8 x 10 print is 5:4.
My camera shoots a 3:2 image, and likely yours does too.
So, if I am printing an 8 x 10, If I have the crop scissor off, my aspect ratio is 3:2. If I turn on auto crop, my aspect ratio becomes 5:4...
So if you crop your print using the Page Editor way (Small image in the little box and drag it around), or this new way, Qimage will remember it for that size ratio. The purpose being.... should you decide you need another two prints next week for grandma, they will be cropped identically and no guesswork.

One last comment.... I generally would crop my "IMAGES" in the image editor. I learned to do it that way when Qimage was a baby.
The image is cropped...  No matter what size print I make (scissor off) all have the same crop. 
On the downside, my odd size crop might look great on an 8 x 10, but turns to drek on a 5 x 7. A very poor ratio match.
Then I have to revise the image crop, and to preseve the 8 x 10, I have to make a second copy of the image with a different crop.
I have been weaning off the image crop. It is easier in 95% of the time to do print crop.

You have really not changed or spoiled anything.  One click on the red X (see screen snaps below) and all is back to normal as before. you cropped.
Hope someone got a little insight into how much is silently built into Qimage, courtesy of Mike.
