  • Do you already have the custom RSS file that shows all the content? If so, what does your code look like?

you can use regular expression on your post content.Which could be done for example like this:

for reference

$content = get_the_content();
// we need a expression to match things
$regex = '/src="([^"]*)"/';
// we want all matches
preg_match_all( $regex, $content, $matches );
// reversing the matches array
$matches = array_reverse($matches);
echo '<pre>';
// we've reversed the array, so index 0 returns the result
print_r($matches[0]);
echo '</pre>';
