Can't get jpeg into sketchup window for Photo match

Hi All- I’m attempting to import a jpeg from my mac to SU window and having difficulty. When I go to File-Import and navigate to the photo file I want, it’s greyed out and I can’t select it. What am I doing wrong? I did get the image I wanted in the window by going thru

Is the extension .jpeg or .jpg? Is .jpg selected as the type of file to import?
