Thanks Matt. As I said, I have a 444 wide image already loaded, and have tried to load it several different ways (via featured image dialog and general image library dialogue), and that is the width of the column (445 actually). But, the image it chooses to show is my 444 image truncated to 222, and then blown up again. You can see this in the name of the image file:
<img width="222" height="300" src="https://www.lavictrola2016.com/wp-content/uploads/2015/10/step-van-color-222x300.gif" class="attachment-give_form_single wp-post-image" alt="step-van-color" title="step-van-color">
So…no matter the size of the original image, it seems to shrink it to 222 then blow it up again.
And, I would much rather put the image to left not above the donation fields.
