Hi all,
I have a list of TVs that use the Image Widget - giving the user a choice of six images that can be added to a template. These images then use PHP thumb to resize.
However sometimes there might only be 2 or 4 images uploaded, therefore on the rendered HTML I only want those output. Currently they are output regardless if the TV has no image.
From my understanding the image widget should not display a TV if it is blank/no value. See here:

This is the sample template call:
<li><a href="#"><img src="[*imageone:phpthumb=`&w=100&h=100`*]" alt="Example of our work" /></a></li>
<li><a href="#"><img src="[*imagetwo:phpthumb=`&w=100&h=100`*]" alt="Example of our work" /></a></li>
<li><a href="#"><img src="[*imagethree:phpthumb=`&w=100&h=100`*]" alt="Example of our work" /></a></li>
<li><a href="#"><img src="[*imagefour:phpthumb=`&w=100&h=100`*]" alt="Example of our work" /></a></li>
<li><a href="#"><img src="[*imagefive:phpthumb=`&w=100&h=100`*]" alt="Example of our work" /></a></li>
<li><a href="#"><img src="[*imagesix:phpthumb=`&w=100&h=100`*]" alt="Example of our work" /></a></li>
Any idea how to programmatically hide those TV’s from output final HTML if they have no value?
EDIT: Solved it myself.
If you are interested here is the call now:
[*imageone:len:gt=`0`:then=`{{imageone}}`:else=``*]
[*imagetwo:len:gt=`0`:then=`{{imagetwo}}`:else=``*]
[*imagethree:len:gt=`0`:then=`{{imagethree}}`:else=``*]
[*imagefour:len:gt=`0`:then=`{{imagefour}}`:else=``*]
[*imagefive:len:gt=`0`:then=`{{imagefive}}`:else=``*]
[*imagesix:len:gt=`0`:then=`{{imagesix}}`:else=``*]
Have a chunk for each image, for instance:
<li><a href="#"><img src="[*imageone:phpthumb=`&w=100&h=100`*]" alt="Example of our work" /></a></li>
Works perfectly
