Jinja image tag with different options - ashish-greycube/help GitHub Wiki

In custom print format,while writing img tag,take care of following points:

  1. We can write in following ways. It will not create an error. 
    <img src="{{ doc.image }}" style="width:10px; height:10px">
<img src="{{doc.image}}" width="50" height="50">
<img src={{doc.image}} width="30" height="30">
<img src={{ doc.image }} width="90" height="90">
<img class="qr-code" src="{{doc.image}}" width="110" height="110">

2. When we want to check if image is exist then only it should appear in print, follow below steps:

 {% if(doc.image) %}
    <img class="qr-code" src={{doc.image}} width="300" height="300">
 {% endif %}


**Notes:**
1. class attribute is not necessary.
2. We can't write  or '' in img tag 
eg. <img src={{doc.image or ''}} width="300" height="300">.
It will create an error of broken image while generating pdf
