Directory path as output when processing single image

[sam210723]

Fails to save image when using an absolute path to an image file as input and absolute path to a directory as output.

Expected behavior

Save image in the specified output directory with the same name (or with -FC suffix) as the input file.

Real behavior

Unable to save image file due to missing output file extension parameter.
"Parameter "extension" must not be empty or whitespace"

Environment:

• OS: Windows 10 64-bit
• Version: 20H2
