Caching the images in HTML for performance?

[Homer Kommrad]

I have HTML files with image elements in it , with urls to other places on internet , nothing local. 

I'm converting the same html incessantly, with changing some text in it every time . 

The problem is that the converter is downloading the same images every time , i believe. And if there was a way to download these images only once , it would be an amazing throughput increase for me .

Is there such an option already ? or a solution ?

No there isn't. But when you are a programmer it shouldn't be to hard to make something yourself.

I did something similar in a solution that I've made with wkHTMLtoPdf. I pre process the HTML before I use wkHTMLtoPdf

Also if someone is willing to do the work, it would not be that hard
to add it to wkhtmltopdf. For most cases it would probably be enough
to create an instance of
QNetworkDiskCache and assign it to the QNetworkAccessManager.

Actually im just using the binary file with  runtime.exec() in java . And using another layer to cache the images seems more suitable to my need i guess
