The pictures I put in there end up ENORMOUS, stretching to fill the space and it ends up way larger than I want. Is there a way to control how big those pictures get without it just stretching or cropping? I’d really rather it resized vs cropped, since I had to turn off header pictures because of the cropping issue.
The images in the boxes have the size configurable in the theme’s options. The featured images for the posts below have the height configurable in the same theme options (their width is not configurable since it’s dependent on several factors, including site width, screen width and layout options).
If you change any values related to images you’ll need to regenerate thumbnails for existing images to be recreated with the new sizes.
