Clicking this link will pop up a white jpg image with grey type on it.
Download that image. It’s a 1920×1080 jpg that you can use as a template for all your homework uploads.
Make copies of it, or make a new template out of it with your info (name, etc.) already in place. Before you upload your assignment, rename the file. Always use a unique name for each file. If you re-use a name, you will overwrite any previous file you uploaded with the same name.
If you need to change the jpg compression to keep the file under a megabyte, feel free, but whatever you do, don’t change the pixel dimensions.
Think of it as a dinner plate. You will use it over and over for many different meals, but you would not change the size of the plate.
Do not right-click the image below. It is only a lo-res representation of the template file. Instead, click on the image to open the full res version (1920 x 1080) in a popup window and save that image to your computer.
