In the configuration from the Simple RSS Feed Reader' Module I have the option to "Image handling (within feed item description)", but how I can show all images? I can only show one!

And is it possible to load all feed first, if the user scroll (Infinite Scrolling)

Hi,

No, unfortunately, none of the features you are asking for are available in Simple RSS Feed Reader.

And is it possible to coding the module that I can show all images?
And where?

Like deactivate the config option?

If you are familiar with programming you can do that. If you do that it would be great if you create a pull request at the plugin repository at github.com/joomlaworks/simple-rss-feed-reader and share your code .
