I’ve the lastest version of wordpress, with the built-in crop tool, but it doesn’t work like i want.
I’ve all thumbnails with the same exact size, but soemtime i’d adjust the automatic cropped, because it’s not always perfect. But if i go in the cropped built-in tool i can’t crop the part of the image i want, because the selected area it’s not proportioned.
For example if my thumb size it’s 300 x 200, and i’d select only the nose of a face, i can reduce the selected part but the resulted thumb will be always with 300 x 200 size. In the same image i’d select all the face, the selected part will be more big, but the result will be always 300 x 200. Now the size it’s fixed, and i can’t enlarge or reduce the zone of my selection.
i hope you have understand.
