Resource/Graphics path

I'm trying to use bookdown in RStudio Cloud for a project that includes external graphics. When I compile to either gitbook or pdf, the .png files are not found and the message is that they are not in the resource path. Is there guidance concerning resource paths in RStudio Cloud, or where graphics files are support to be. Even adding them to _book/_main_files.figure-html doesn't help. This is also true with a simple rmarkdown project, without bookdown.

Hi. Could you please submit a reproducible example in the form of a reprex? That will help us understand and investigate your issue. This post contains guidance on how to create a reprex if you are not familiar with the process.

Best,
