I have near 800 post/page in my site and 3800 images. I actually set Large Size to 600px width but in my new theme i want my image width be 880px.
So i would like to switch all my image to Full-Size and don't do that one by one. :D
Have you any idea to do that ?
I try to delete Large, etc, but always have 404 with :
in my post instead of
Thank you for the delete and sorry for the bad English i'm french.
