How do I loop correctly through a 2d array?

because obviously i am doing it wrong <img src="{SMILIES_PATH}/icon_e_wink.gif" alt=";)" title="Wink">

I have a 2d Array with a width of 20 and a height of 4 and it has random values from 0 to x: http://prntscr.com/7nly9m

When it's not 0 then I want to display an image with the correct id (product id = value in array). This works all fine. The correct images are being shown but for some reason it multiplies them several times. As you can see here: http://prntscr.com/7nlz0e

Here is the code: http://prntscr.com/7nlz4m

Thanks for your help!

This is running every tick. Move it into "On start of layout" if you just want it run once.
