 * The following eight settings can be used to invalidate an upload if the file is an image (note that <i>open_basedir</i> restrictions prevent the use of these settings)

 *  <li><b>image_ratio_crop</b> if true, resize image conserving the original sizes ratio, using {@link image_x} AND {@link image_y} as max sizes, and cropping excedent to fill the space. setting can also be a string, with one or more from 'TBLR', indicating which side of the image will be kept while cropping (default: false)<br>
 *  <pre>$handle->image_ratio_crop = true;</pre></li>
 *  <li><b>image_ratio_fill</b> if true, resize image conserving the original sizes ratio, using {@link image_x} AND {@link image_y} as max sizes, fitting the image in the space and coloring the remaining space. setting can also be a string, with one or more from 'TBLR', indicating which side of the space the image will be in (default: false)<br>
 *  <pre>$handle->image_ratio_fill = true;</pre></li>

 *  <pre>$handle->image_ratio_y = true;</pre></li>
 *  <li><b>image_ratio_pixels</b> if set to a long integer, resize image, calculating {@link image_y} and {@link image_x} to match a the number of pixels (default: false)<br>
 *  <pre>$handle->image_ratio_pixels = 25000;</pre></li>
 * </ul>
 *  The following image manipulations require GD2+
