Hi Sara

Thanks for posting in the Lucidchart Community! I'm not sure I understand exactly what you'd like to do in Lucidchart so please let me know if the following does not answer your question! You can take a screenshot in Lucidchart using your computer's screenshot commands or snipping tool. To do this open Lucidchart online open a document and take a screenshot/use the snipping tool as desired. You can also add images directly into Lucidchart. If you've taken a screenshot of something you'd like to add to your document you can insert images into your document by following the instructions found in our Add and customize shapes in Lucidchart article.

I hope this helps! Let me know if you have any other questions or if this does not answer your question completely!
