										<h2>General Options</h2>
										<p>SEO Friendly Images automatically adds alt and title attributes to all your images in all your posts specified by parameters below.</p>                         
										<p>You can enter any text in the field including two special tags:</p>
										<ul>
											<li>%title - replaces post title</li>
											<li>%name - replaces image file name (without extension)</li>
											<li>%category - replaces post category</li>
											<li>%tags - replaces post tags</li>
										</ul>
										<h4>Images options</h4>
										<div>
											<label for="alt_text"><b>ALT</b> attribute (example: %name %title)</label><br>
											<input style="border:1px solid #D1D1D1; width:165px;"  id="alt_text" name="alttext" value="$alt_text"/>
										</div>
										<br />
										<div>
											<label for="title_text"><b>TITLE</b> attribute (example: %name photo)</label><br>
											<input style="border:1px solid #D1D1D1;  width:165px;"  id="title_text" name="titletext" value="$title_text"/>
										</div>
										<br />
										<div>
											<input id="check1" type="checkbox" name="override" $override />

										<div>
											<input id="check2" type="checkbox" name="override_title" $override_title />
											<label for="check2">Override default Wordpress image title</label>
										</div>
										<br /><br />
										<p>Example:
										<br />
										In a post titled Car Pictures there is a picture named Ferrari.jpg<br /><br />
										Setting alt attribute to "%name %title" will produce alt="Ferrari Car Pictures"<br />
										Setting title attribute to "%name photo" will produce title="Ferrari photo"</p>
