apart from Dimitri's answer, another possible solution requires a bit of coding from yourself. You can replace the component, that identifies the embedded resources. Have a look at The JMeter property htmlparser.className can be used to set that component. Unfortunately all the built-in components behave as Dimitri explained. They look for the standard resources. You are free to look at the currently implemented components and extend them (copy/modify/sub-class) to your specific need.

Hi,

Why would JMeter download the image given it doesn't have *src *attribute? This *data-src* doesn't have any meaning neither for JMeter nor for browser hence it's being ignored (as well as any other data-* attribute <https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/data-*>)

If your web application uses this "data-src" for some form of lazy loading <https://en.wikipedia.org/wiki/Lazy_loading>unfortunately there is no easy way to instruct JMeter to parse custom attributes which don't have any behaviour which is described in the specification <https://datatracker.ietf.org/doc/html/rfc1866#section-5.10>

So you have the following options:

1. Fetch URLs of the images having this "data-src" attribute using CSS
   Selector Extractor
<https://jmeter.apache.org/usermanual/component_reference.html#CSS_Selector_Extractor>
   and then simulate the download using Parallel Sampler
<https://github.com/Blazemeter/jmeter-bzm-plugins/blob/master/parallel/Parallel.md#parallel-sampler>
2. Create your own version of HTTP Request sampler
<https://www.blazemeter.com/blog/how-to-develop-a-jmeter-plugin-intro-and-best-practices>
   which will be handling the images with "data-src" attributes
   according to your web application business or technical requirements.

Hello,

JMeter does not seem to be able to download an embedded image with this
kind of html tag:

<img class="xxxx" data-src="https://yyyy/image.jpg?sw=433&amp;sh=635&amp"; />

Is it configurable ?

Thanks
