258 -To use the image widget, you should first add an image to your project. The image format must be PNG, and its resolution should not exceed 800x480 pixels. There are two ways to add an image file. One way is to move your image into the folder "…/squareline project/assets/", as shown in image 10. The other way is to click the "ADD FILE INTO ASSETS" button, then select an image from your computer to import. After adding, you can see the image in the "assets" area in SquareLine Studio, as demonstrated in image 11.

269 -==== **The relationship between widgets** ====
270 -
271 -
272 -Widgets commonly have two types of relationships: **parallel** and **parent-child**.
273 -
274 -* In a **parallel relationship**, widgets' positions are determined relative to a shared reference object.
275 -* In a **parent-child relationship**, any part of the child object outside the parent's boundaries is hidden by default. To make the child object fully visible, you must adjust its position to fit within the parent's range, as shown in Image 13.
