+<h3>Resize large images on upload</h3>
+<p>If enabled, any images which are larger than the height and width specified will be resized to fit the size limit.</p>
+<p>This is highly recommended for images intended for normal display in a web browser. Very large images (e.g. straight from a digital camera) are slow to load in the browser, and take up unnecessary disk space, quickly using up your quota.
+There is also no discernable gain in quality when viewing on a typical monitor.</p>
+<p>However, you may wish to upload the original <strong>without</strong> resizing if you are sharing an image for printing.</p>
+<p>You can choose the default setting for this option on your Settings page.</p>

+<h3>Resize images on upload - maximum image size</h3>
+<p>Maximum image size specifies a maximum pixel height and width for a user’s uploaded images. All images uploaded will be resized to these dimensions if they exceed the maximum image dimensions and image resizing is enabled.</p>
