[Emily]

I can see you didn’t even try the website I linked, if you’re not willing to put such low effort I can’t help you, your files are both 3248KB, the max file size is 1000KB:

File Too Large, But It 100% Isn't

The max file size is 1000000 bytes, and the image file you linked is 1006826 bytes, thus putting it over the filesize limit.
