Recovering 'lost' or erased images on an SD Card

This afternoon, I took four pictures of a commercial airliner flying south overhead, and when I resized those, expecting the resizer to simply duplicate the images in the newer size, it didn't, because it's an older version on this PC than on my other one. I really wanted to keep the bigger sizes as well, so this began a search for a free recovery tool to recover images from an SD Card. The images were on the camera card originally, and I hoped this might work. It not only worked perfectly, but it found not only the four I wanted from today, but a total of 21 images altogether on that card, and the picture quality of the recovered images is really good. I can hardly believe it. Here's an example of an older image from the card, one that has been on there a long time...

You can find the program here if you would like your own copy. Click on the big blue button 'Download' in the upper frame of the window, where the title reads "Free File Recovery Software". That takes you to the download page, where I didn't have much luck clicking on their "Download Now" recommended button, but I did get nice results using the one for Pandora's own Server, where it says "Download from local server...." - and this is a really nice program, which does just what it promises to do. It recovers your images, even including some you weren't really looking for, like this one above. But you must admit, nothing was lost in the process; that's a perfect duplicate of the original photo, and I'm really impressed by it.

Here's what started all this..... this jet coming over our mountains....

And here's why I wanted the 'lost' larger camera images back:

So I could show you the plane that was making that trail across the sky.
