Applies a lightbox to all image links if and only if the screen is big enough to fit a lightbox. 
Because lightboxes on iPhones should be illegal.

Conditional Lightbox

Use a lightbox only if the screen is big enough.

Minimizes the comment list and turns the comments title (eg. “3 Comments”) into a trigger to view/hide the comments.
Requires no template hacking, only a knowledge of CSS selectors:
<ul>
<li>The comments are usually inside a list with a class of “.commentlist” so you probably won’t need to change the option for the “contents”.</li>
<li>The comments title however may be different on your theme so you may have to change the “trigger” option to something different than the “#comments-title” id. Use “Inspect element” on your post’s page to deterime the correct class or id of the element you want to be the trigger.</li>
</ul>
