Detect image in FileUpload to hide upload instructions

I'm having trouble with changing the avatar after I upload it using the FileUpload field. Here's what's happening: - When I upload an avatar and then reload the page, I see instructions to "drop or click to upload an image" on top of the avatar I just uploaded. I shouldn't be seeing this. - Also, I can't click the "x" to remove the avatar because the instructions cover it up. It looks messy. - But, if I change the avatar and stay on the page without reloading, this problem doesn't happen. I checked the Demo app, and this issue isn't there, so I think I might be missing something. Can you help me figure out what's wrong? Thanks a lot!
