Add some relevant pictures to give a little bit of context, or to cheer up the reader.

web browser on a computer, you're not reading a book on a Kindle.

Answer 1

change your IMG Style Like this
div.psp div.picture-left img {
width: 100%;
margin-right: 1em;
float:left;
}
then add css class .picture-left
like this
.picture-left {
width:45%;
}
then add CSS class .psp like this
.psp{
display: flex;
}
try this if you have any doubt comment me
and don't use bad words on public platform posts✌
div.psp div.picture-left img {
width: 100%;
margin-right: 1em;
float:left;
}
.picture-left {
width:45%;
}
.psp{
display: flex;
}
div.psp div.picture-left figure figcaption {
font-size: .7em;
}
<h2>Put some pictures</h2>
<div class="psp">
<div class="picture-left">
<figure>
<img src="https://images.pexels.com/photos/104827/cat-pet-animal-domestic-104827.jpeg" title="A nice and cute cat" alt="white and gray cat looking at you, with his yellow and green eyes" />
<figcaption>A cat, just to keep the context of the website.</figcaption>

Answer 2

It happned because you floated the image to left.
Thats why it is going on the side.
Just don't select the img tag, Like this:
div.psp div.picture-left { /* <---- Just remove the img */
width: 45%;
margin-right: 1em;
float:left;
}
div.psp div.picture-left figure figcaption {
font-size: .7em;
}
