Yes. For some reason my `!empty()` approach didn't work with this because the format ended up coming out different. Turns out `$values['field_avatar']['und'][0]` always existed even if there was a photo. I did a `dsm()` and found that `$values['field_avatar']['und'][0]['display']` was always valid in this case and would return `true` or `false` depending on whether or not an image was uploaded.
