When I click on the image thumbnail, it goes to the image detail page. But how to change this behavior to just redirect to other website url, something like <img src="http://...." target=_blank>

I just know an field (image URL) should be added into the image database. It is more like an advertise item.

Is there any how to, or detailed instruction on this request?

The effect is expected to be like the www.beso.com
see attached picture.

All the images are actually directing to another page (I want a URL directing to other site). Also, there are some other information like product title and price is shown.

thanks,
Larry
