here's image of some thumbnails in my wordpress homepage: http://i.imgur.com/x8EmtMO.png
The first one is resized very nicely - I don't know why and how - and the other ones are cropped in the center like it's default in wordpress settings.
So here's my question: how to resize or resize and crop the images to be like the first thumbnail? I came close with the solution using plugin Post Thumbnail Editor, but there were blanks spots above and under the thumbnail which made pretty huge vertical spacing between the posts.
I'd appreciate any answers.
