Force article_image field to accept multiple images without a plugin

Plugins come and go but also bugs are suppressed. The code is based on a bug/feature of Textpattern where the article_image field also behaves as a custom_field. There are a number of plugins which can achieve this but here is a native method.

Assign article_image to a custom field

<txp:article_custom id='<txp:article_id />'>
	<txp:variable name="aimg" value='<txp:custom_field name="article_image" />' />
		<txp:if_variable name="aimg" value="">
		<txp:hide>if there is no value in the article_image field show nothing</txp:hide>
		<txp:else />
		<txp:images id='<txp:variable name="aimg" />' limit="10">
			<txp:image />

All one needs to do is add the a comma separated list of article ids in the article_image field and the images will show in the page.
