JFile: :copy: Cannot find or read file

Hello

I'm having a problem uploading photos to properties on live hosting.
When I click on browse photos and save, I get the following error:

JFile: :copy: Cannot find or read file:

I did some research, and all indicate that it's a GD library issue.
But when i do phpinfo(), it says that GD library is enabled and jpeg support enabled. (see attached file)

So I don't know what to do next. Any ideas please?
Thank you so much for your help.
