click on your pic and it should show up in “preview”. click “tools” then “show inspector”. your pic attributes will be visible. “image size” should be no bigger than 4,000 x 4,000 pixels. “image DPI” should be 72 unless you doing a zoom and pan on the pic. i use 100 and it works well. “color model” should be RGB. i use Photoshop to adjust these parameters. also…in your timeline..under “sequence” click “video processing” and you should set it to “always render in RGB” if it is on “render 10 bit material” it will take hours and you will probably get an “out of memory” flag. good luck.
