By default, if an appropriately sized thumbnail is not available in WordPress, a larger image will be served and will be made to fit in the thumbnail space via CSS. Sometimes this means images will be scaled down in a weird way, so it is not ideal. What you really want is for YARPP to serve appropriately-sized thumbnails.

= How can I move the related posts display? =
63
64
+ If you do not want to show the Related Posts display in its default position (right below the post content), first go to YARPP options and turn off the "automatically display" options in the "website" section. If you would like to instead display it in your sidebar and you have a widget-aware theme, YARPP provides a Related Posts widget which you can add under "Appearance" > "Widgets."
65
66
If you would like to add the Related Posts display elsewhere, edit your relevant theme file (most likely something like `single.php`) and add the PHP code `related_posts();` within [The Loop](http://codex.wordpress.org/The_Loop) where you want to display the related posts. (Make sure you don't add `echo related_posts();` or you may end up with duplicates in your related posts section.)

Each time you change YARPP's thumbnail dimensions like this, you will probably want to have WordPress regenerate appropriate sized thumbnails for all of your images. I highly recommend the [Regenerate Thumbnails](http://wordpress.org/extend/plugins/regenerate-thumbnails/) plugin for this purpose.
