I want to change my image size. Large is now 600px wide but I want it to be 800px wide.
In many pages I have embedded images like this:
<img class="alignnone size-large wp-image-261" src="http://xxxxxxxxxx-600x456.jpg" width="600" height="456" />
I changed the size of large images in the media settings and regenerated the thumbnails. When I embed a new images into a post it works well. But all the old ones need to be updated.
I have too many pages to do it by hand. Is there an automatic way to do this?
