PNG image has some background image

[bwood]

I didn’t know what to call this but it’s happened before and it’s user error. I’m constructing a new page and don’t want to make the same mistake.
You’ll notice on the screen shot, the oval with text has taken on the background of the photo. I first thought I had copied and moved the oval to a new location, thus taking some of the photo background with it. I believe that’s what I did. Would I solve this by putting the oval on a separate layer?



The entire page can be viewed here. https://www.melfortmuseum.org/indigenous%20peoples.htm

Thanks everyone
