Give optionally width:100% for Content Display: Slider View

[v-o-v-a-n]

Content_Display: Slider_View

picture in real size. instead of 100% width and no height limit, if for example there are several pictures of different sizes in the slider, then the slider changes height when scrolling.

lets hide two lines so that the width of the photo in the slider is 100%.

<div class="slick-list draggable" style="height: 481px;">
<div class="slick-track" style="opacity: 1; width: 10710px; transform: translate3d(-1190px, 0px, 0px);">
<article class="advgb-recent-post slick-slide slick-current slick-active" data-slick-index="0" aria-hidden="false" style="width: 1190px;" tabindex="0" role="tabpanel" id="slick-slide00" aria-describedby="slick-slide-control00">
<div class="advgb-post-thumbnail">
<a href="..." tabindex="0">

/wp-content/plugins/advanced-gutenberg/assets/css/recent-posts.css

.advgb-recent-posts-block .advgb-recent-post .advgb-post-thumbnail a {
    display: inline-block;/* hide this so the image is 100% wide  */
    max-width: 100%; 
}

<img width="1" height="1" src="..." class="attachment-large size-large" alt="" decoding="async" loading="lazy" data-wp-pid="908">
/wp-content/plugins/advanced-gutenberg/assets/css/recent-posts.css

.advgb-recent-posts-block.slider-view .advgb-recent-post .advgb-post-thumbnail img {
    height: auto;
    width: auto; /* hide this. lets make optional width: 100%;*/
    margin: 0 auto;
}

Make a checkbox: “image slider width 100%”. So that, depending on the need, you can turn it on or off.

Make a field: “picture slider height” and crop photos about the height, if the height is higher than the specified one with a picture width of 100%.

Let’s say I will use a slider for posts with large photos. What if my photos will be less than 100% in width or different proportions?
