Im super confused with what elements is

I had subscribed to elements thinking I could download the cool graphic designs and use them for my own needs.
But every time I download one, its seems that it doesnt include any of the graphics that made it look so good in the preview.
So, Im really not sure what elements is.
Maybe I need to contact the designer and buy the whole design or something?

Almost all items don’t include the demo images

Very rarely the author will have license and ownership rights to redistribute these

If you contact the author then they may be able to tell you where you can get the images though
