Please do not overwrite files
I noticed that you uploaded a file using the name File:Barselona052.JPG. A file by this name already existed on Commons. Overwriting an existing file should not be done except when making minor, uncontroversial corrections, so the file has been restored to its original version. If the file you attempted to upload is within our project scope and is in the public domain or published under a free license, please upload it again under a different name. Thank you!
For more information, see Commons:Avoid overwriting images with new uploads.
