Oh, hmmm, thats not super easy to do
Create a new text, just write "Hey".
Give the textfield a class "test-img-wrap" using the "class" button (here's where to find the class button: http://laytheme.com/documentation.html#custom-css-styling )

Now edit the text and put text and images into a textfield using the <> code button. I'm using the class "img-in-text" for every image
<p>Hello</p><img class="img-in-text" src="https://upload.wikimedia.org/wikipedia/en/d/d4/Mickey_Mouse.png" /><p>Hello</p><img class="img-in-text" src="https://upload.wikimedia.org/wikipedia/en/d/d4/Mickey_Mouse.png" /><p>Hello</p><img class="img-in-text" src="https://upload.wikimedia.org/wikipedia/en/d/d4/Mickey_Mouse.png" /><p>Hello</p><img class="img-in-text" src="https://upload.wikimedia.org/wikipedia/en/d/d4/Mickey_Mouse.png" />

Now put some CSS into "lay-options" -> "custom css":
.col img.img-in-text{
display: inline-block;
height: 100px;
width: auto;
position: relative;
}
.test-img-wrap p{
display: inline-block;
vertical-align: middle;
}
And thats what it looks like:
