Hi I can't get a jpg or whatever it's called into here. Can anyone help?

Have you tried the    ' image ' button to upload a pic?

Right-click on the file and go to rename.

Rename the end of the file from jpg to pdf.

so if your file name is "image.jpg"

rename the file from "image.jpg" to "image.pdf"

I learned this while trying to figure out how to make my google background a gif. It took me a while since this is the school's Chromebook ( Or because it's a Chromebook).
