This little Joomla tutorial shows how to link the article intro image in your joomla category blog to the full article. Default it is only possible in the current Joomla 3.3.6 to show a read more link that links to the detail article page.

Attention: do not change joomla core files, otherwise they’ll get deleted when you update joomla core

I read this article on Stack Overflow but that didn’t solve my problem: http://stackoverflow.com/questions/19654706/joomla-3-1-intro-image-as-read-more-link
