Permission Errors in cPanel

[DeiseHost]

move /home/freejoom/tmp/Cpanel_Form_file.upload.H3N_5O4eBZDqnAVM to /home/freejoom/public_html/templates/fjd/images/powered_by.png failed: Permission denied
powered_by.png (powered_by.png): upload succeeded, overwrote old file.

That's what I get when I try to overwrite an image in cPanel.
I get similar permission failure warnings when trying to change permissions or modify a file.

Please advise.

check the ownership of files. You must be the owner of these files in order to change the permissions.
