Dear Mr. Andrew,
I upload the images to my posts normally through add media and when I hover over any image by the mouse I see this code at the end of my image's URL in the status bar of my web explorer, and also when I right click on any image and chose view image info I see all my images' URLs with this code at the end!
I don't add it and I don't know how that happens!
I understand from your kind reply that there isn't any problem in my site.
Do you know how to remove this code from my images' URLs
Thanks for your help.
