	Auto-Configure
</h3>
<p>
	Autoconfigure is the method of setup recommended for most users. It works on most shared hosting providers. Autoconfigure will do the following, in order:
	<ol>
		<li>
			Create a cache directory in your uploads folder.
		</li>
		<li>
			Configure PostsByImage to use the newly-created cache directory.
		</li>
		<li>
			Generate the image cache for your existing posts and pages.
		</li>
	</ol>
	<input type="submit" name="autoconfigure" value="Run Autoconfigure" />

<h3>
	Image Cache Generation
</h3>
<p>
	Clicking the button below will regenerate your image cache. You should only have to do this once (immediately after installing the PostsByImage plugin). Please note that this process can take a lot of time--if your server is slow or if you have a lot of posts it may take several minutes!
	<br />
	<input type="submit" name="regenerateimagecache" value="Regenerate Image Cache" />
</p>

<h3>
	Image Cache Storage
</h3>
<p>
	Generated images will be stored on your server in the directory below.
	<br />
	<input type="text" name="cachepath" value="<?php echo stripslashes ( get_option ( 'ds_pbi_cachepath' ) ); ?>" size="<?php echo strlen ( stripslashes ( get_option ( 'ds_pbi_cachepath' ) ) ); ?>" />
	<br />
</p>

<h3>
	Image Cache Accessibility
</h3>
<p>
	Images stored in your cache are accessible in the URL specified below.
	<br />
	<input type="text" name="cacheurl" value="<?php echo stripslashes ( get_option ( 'ds_pbi_cacheurl' ) ); ?>" size="<?php echo strlen ( stripslashes ( get_option ( 'ds_pbi_cacheurl' ) ) ); ?>" />
</p>

<h2>
	Display Settings
</h2>
<h3>
	Columns per Table

<p>
	Number of columns in your display table:
	<input type="text" name="defaultcols" value="<?php echo stripslashes ( get_option ( 'ds_pbi_defaultcols' ) ); ?>" size="3" />
</p>
<h3>
	Thumbnail Dimensions
</h3>
<p>
	<em>
		Note: Changing these values will only affect newly-generated thumbnails.
		<br />
		To change the size of existing thumbnails, regenerate your image cache after modifying these settings.
