When adding a background image to a space (in this case, the Laubichler lab home space), the image resized and became very blurry. Image file type was .jpeg, which I changed to .png before uploading. I uploaded several different original sizes for the background space, anywhere from ~5"x4" to ~20"x16". The image was either blurry or appeared clear but very small (about 1 inch in length) in the upper left corner. Original image below.

Final result:
