This plugin fetches the first image of the topic and sets it as the featured image, showing in the topic list and above the main topic.

hmm how is this any different to?
possible ideas for upgrade:
is it possible that the thumbnail image get truncated rather than resized, in the main page? then as one goes on it, it becomes click-able and after click, the whole image (not cropped) being shown. this way one can keep the aspect ratio of all the images similar, and the main page looks better.
This plugin reads an image even after writing before text?
Example:
"Text
-image-"
beside the magnification part, it's currently doing that via CSS so it's easily overridable with something of your liking.
Right now is set to object-fit: cover; so is already cropping.
Yes it does. Fundamentally it gets the first image that is uploaded
is it possible to have a default image which is set to default for those posts that doesn't have images?
otherwise those posts will make the design little bit unhappy.
I was thinking about this problem the other day.
There are several ways to deal with this issue, putting a default image, setting a color instead of the image or not having the white space.
Ideally I will like to solve it with CSS so that who manage a website can make the decision of how to handle it.
I will investigate more into it.
great 
if one can put an image from the assets of site design for the empty posts, then he/she can decides what the image would be, and empty colored box or an image.
how to increase width of image? Thanks!
you should be able to do it simply with CSS
i try:
img.list-item-featured-image {
width: 80px;
height: 60px;
}but no working!

what should I change? @emanuelet
In the link that you passed I don't see any of the classes from my plugin.
I'm assuming that you're using the Topic List Previews plugin.
Anyway regarding the CSS, what I would do is check with Chrome Dev Tools where your overrides are sitting in the order of priority.
Than to be sure that it uses what you defined you can apply !important to the properties.
I'm testing the two plugins, the topic list previews bug my categories search, I not know why, I'll reinstall your plugin to insert the !important and try again! Thx!
@emanuelet after installing plugin disappeared the category names in the header, and my youtube videos no longer appear!
