Multiple Layers side by side

We create a new file (640X320) and we open the images that we want to add in the new file as layers.

First layer (freeImages/chocolate-2202123_1920.jpg)

We add the transparency property and we make the image transparent. Also, we use the "scale layer" to change the width to 320px.

Second layer (freeImages/chocolate-567234_1920.jpg)

We repeat the same procedure that we did for "First layer".

Third layer (freeImages/ballon.png)

This layer is already transparent, so we change only the width.

Final settings on layers

Here we see an example of the usage of the "autocrop" property, and "align" and "move" tools on the layers. 

Final settings for the background image (transparency, crop).
