One thing to note is that when you use this method to make the image fit, it can make it look a little choppy. But it's an OK workaround if you're not able to upload it in the exact size you want.
Thank you so much! That worked great! It looks just like what I wanted.
You're a peach, I tell ya! An absolute gem!
