「differences」for Question

Main element
An image is used as the main element when the resource is used in a product (physical or digital) as it has been downloaded from our site, without any changes being applied to the design.
It will also be considered the main element when small changes are applied to the design, like changing the color or orientation.
If you add other elements created by yourself or by a third party, like small details or adding/changing the text, but the design from our sites is still the element with more weight in the final composition, meaning that it attracts the attention before the other parts on the design, this will still be understood as the main element.

Secondary element
ACworks resources are used as secondary elements when other elements, not from our sites, are added to the final composition and become more important than the resource from ACworks.
Please be noticed that using multiple images from our sites is also considered the main element, so you need to add other designs created by yourself or from a third party.

If you want to use a background from our sites to add other elements on top, like a message in fancy typography, please note that you must choose a background that has less weight than the text you add, like a watercolor or an abstract background.

If you choose a background with a floral frame or an illustration and just change the text it will not be enough.

Patterns cannot be used to create products like clothes, notebooks, or wrapping paper if these are to be used commercially, since these are considered main elements. You would need to create a new pattern, adding other elements not from our sites to the design.
