Image does not show in article and gallery pages

[mondingnibai]

I successfully created a plug-in. I have also a template called show_image, this show image is located below the navbar. I want to show a image right here, so I create a plug-in and call the variable I declare in the show_image. It works, but in the article page and gallery page does not. what would be the problem here?

Here's the plug_in code:

ob_start();

include('image.php');
$my_image = ob_get_contents();
ob_end_clean();

vB_template:: preRegister('show_image', array('my_image' => $my_image ));

What hook location are you using? If you go into debug mode and go to the articles or gallery page, see if that hook location is even called on those pages.

Yupz those pages or templates are called.I am using the global_start hook location.

global_start is not present in CMS. Try using parse_template or one of the global_bootstrap hooks.

As Cellarius stated, the global_start hook is not present on the CMS pages. You need to look at the list of "Hooks Called", not under the list of "Included Files".
