button on the toolbox or right click on the image and follow the menu
<span class="guimenu">Tools</span> ‚Üí <span class="guisubmenu">Transform Tools</span> ‚Üí <span class="guimenuitem">Crop and Resize</span> in the image window. This will change
the cursor and allow you to click and drag a rectangular shape. The
button in the toolbox is the nicest way to get to any of the tools. I
have chosen one of the huge and beautiful APOD images

I always click on the approximate upper left corner and drag to the
lower right corner. You don't need to worry about being accurate on this
first swipe with the crop tool, since a little dialog will pop up and
you can make a better choice for your new borders there.

After completing the click and drag motion, a little
“<span class="quote">Crop and Resize Information Dialog</span>”
(shown above also) pops up, telling you information about the borders
that were defined in the click and drag. We will have to change all of
the numbers. If you would like to make this rectangular image square,
you should find the width and height from the Get Image Information
Quickie (see <a class="xref" href="gimp-tutorial-quickie-info.html" title="4.5.  Find Info About Your Image">Section 4.5, “
<span lang="en" xml:lang="en">Find Info About Your Image</span>
”</a>.
Use the smallest of the two lengths to determine the size of the
square. In my 300 x 225 pixel image, the largest square I can get is 225
x 225 pixels, and I will need to make sure the Y origin is 0. At that
point, I use the image and the squares to get the best part of the image
for the area. The upper right and lower left crop squares will move the
marked area. The other two (upper left and lower right) will change the
dimensions of the marked area, so be careful. I have a screenshot of
this, right after I fixed the width and height and the Y origin, but
before the final positioning. The arrows show the move points.
I decided that the image looked the best with the X Origin at 42.
