Feeble and lacking :-)
I have been using Photoshop Elements since I bailed on the (feeble and lacking) Pentax software when it was v3.51.
I recently bought the DVD of v15, when it was on sale for $59.99, which included the Windows and Mac versions. It has 3 "modes" ranging from Basic to Expert. In expert, you can adjust the various sliders to taste, then open the image and do more things or just save it. If you don't want to get fancy you don't have to. There is a lot of tutorial info on the web, but a little trial and error on the main features and you should be good to go.
Otherwise, I would recommend
FastStone Image Viewer, Screen Capture, Photo Resizer ..., but it is Windows-only (and free).
Most of all, continue to read the threads in this section as it has all been answered, somewhere.
