When you’re inserting the image, you’ll see a dropdown menu in the bottom-right corner that allows you to select the size of the image. Select the “full-size” option, and center align the image. It should then fill the width of the post content container.
sadly it didn’t work. I’m trying editing, placing new image, manualy resizing, making link from image… Nothing works. I even set sizes for thumbnail, medium and big, and from medium is above 715px.
So i don’t know. Trying find css for this but no succes here.
Okay try the following CSS:
.aligncenter, .alignleft, .alignnone, .alignright {
max-width: 100% !important;
}
I think that should do the trick.
