Imported images don’t show up

I am really new here! I am importing png into the letter box and it shows up fine!
Then I am saving the file and the moment I reopen, nothing showes up. I can select the image I added, but it want display! Plz help

Is the image file stored next to the .glyphs file?
Is View menu > Show Image checked?

Show image is checked and about image file and glyphs file i dont know what you mean… I would simply love to import a png and use it as a glyph. Or any other file… it must be possible

Btw, is there auto trace possible… of an image

Can you send me a glyphs file and an image?
