    1. COThanks, what i should specify though is that i do understand how to pass a variable from one page to another, what i don't get is how can i get the 'id' of the image to be placed in to a variable in the first place once the user clicks on an image? if that makes any sense? :S

    3. COSome awesome stuff, i have tried using this, it all works until i add images, thats how i've done it 'echo "<a href=\"page.php?id={$row['id']}\" />{$row['name']} <img src=\"{$row['img']}\> </a>";' but now every link only links the id 1 and only shows 3 images instead of 4, any ideas why?

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
