Image Resizer

Steps to reproduce

1. Create a new Image Resizer preset within the Settings application of 4000 by 4000 pixels with a Fit setting of "Fit"
2. In Explorer, right-click on any image smaller than 4000 x 4000 pixels
3. Select "Resize with Image Resizer" to open Image Resizer
4. Select the preset created in Step 2
5. Ensure "Make pictures smaller but not larger" is checked
6. Click the Resize button

✔️ Expected Behavior

Either:

1. No work is done because the image already fits within 4000 x 4000 pixels and does not need to be resized, or;
2. The original file is copied, following the filename format and file modified settings defined in the Settings application

❌ Actual Behavior

The image is 'resized' but with the same dimensions as it was originally. For lossy codecs like JPEG, this results in a generational degradation in quality.
