Tables and Charts transfer from web pages.

For a research paper I am using certain charts and tables found on related web pages. Some I can transfer to the Scrivener document by copy and paste. Others I have to make into pdf and let Acrobat’s “graphic select tool” produce the boundaries for cut and paste. Some of the pdf that I move intact into Scrivener’s Research folder can be copied or cut and resized or repositioned in the document somewhat but not always.

The question here is: does anyone know of a better or alternative way to move data or graphics from web pages into the Scrivener document?

Thank you for the assistance.

Also I thank the developer for an outstanding piece of thinking underlying a so far trouble free and powerful writing resource.
