Scheduled post bigger images

I recently start using scheduled post (draft.blogger.com), and I usually put some images in the post. After viewing, I found that images inserted in the post seemed to be larger. Of course, this will take up space of the article column. But you can't resize the image in the post when you post in draft.

To solve this problem, I usually resize the images manually, so that it can fit better and equally among text. Hope this tip help a little to those who like post in draft.
