In oik v4.1.0 we removed a line from the oik.css
file.
img { max-width: 100%; width: auto/9; /* Prevent stretching of full-size images in IE8 */ }
This line of CSS was required by Artisteer themes, up to version 4.3. It prevents images from being sized larger than their maximum width.
If you still use an Artisteer theme you may find that you have to add some new CSS to your custom CSS solution. e.g.
Restrict images in Artisteer themes from being larger than their maximum width.
img { max-width: 100%;}
div.bw_image img { max-width: 100%;}
Additional notes
oik-plugins no longer use Artisteer to generate themes. Support for Artisteer generated themes is only maintained for backwards compatibility. For non Artisteer themes the [bw_images] shortcode doesn’t require this additional CSS to limit the image size.
