Resize your blog images on blog theme change with CSS

If you want to change your blog theme and the post width is reduced in the new theme, you may have a problem with previous posts. For example you have your old theme with full width image of 600px and in your new theme, your post entry width is just 500px, then your old images will jump out of the post area. Its practically very difficult to edit all the images and get the sizes change.

This simple CSS styling will sort out your issue

.entry img{ max-width:480px; height:auto; }

entry is the class name of the post content where image is displayed
