Well, my problem is simple, but WordPress is having some problem with that, it seems. I upload my imagens and then I go to the gallery to insert all them into the post. The problem is not at the thumbnail that appears in the post. The problem is that when you click in the image, to suposely see the full-sized image, I get a medium-sized one.
I noticed that when you click at the medium size image to see the link, it ends like that: xxxx.jpg?w=(number here). Ex.: xxxx.jpg?w=93 - And if you delete the 'w=(number here)', you get the full-sized image.
My question is simple: is there a way to see the full-sized image, not in the post, but when you click at the thumbnail in the post? I mean, without the 'w=(number here)' in the link?
