I have tags enabled on the image field, so why am I getting this error?

What is $block? What is pg? Is the image field actually called 'images'?

$block is a single item in the repeater field "home_blox". $block->pg is the Page field within the repeater. Image field is named "images".

This worked:

	foreach($page->home_blox as $block) {
		$bgimg = '';
		$pg = $block->pg;
		if($pg->images->getTag('blockbg')) {
			$bgimg = "<img src='{$pg->images->getTag('blockbg')->url}'/>";
		}
