Forum:Defining the image for "Read more" section

I am actually trying to change the image, that is chosen automatically for an article's "Read more" link. Do you know a working method?

I wrote a template some time ago like this to add an additional invisible image at the top of an article, for avoiding using (downscaled) message box icons, and I'm pretty sure it worked on articles with few images. But now I have here an article with several images, and the template doesn't seem to work. I have the impression, that "directly" included images are favored over images, that are included by a template. Is that possible?

The article I'm referring to can be found here. I want the "Read more" link to show the infobox image instead of the other book cover, that can be found in the section "Publishers in other countries".

Do you have experience with this problem? Thanks in advance. -- Weas-El  Talk|Contribs  18:34, March 26, 2011 (UTC)
