Hi, When I add new media in a post, by default it add the url src ended by 300… so the image is to small.
-300x150.png" alt="" width=“300” height=“150” class=“alignnone size-medium wp-image-204”
If I delete the -300x150 It shows in the real size, but if I to put width=“100%” it doesn’t work as in other templates.
When you add a new image there is an image option on the lower right hand side of the window that appears, called the Attachment Display Settings > Size and this would allow you the set the size to be used for the image.
