It depends on what you mean when you say “pull in,” and “images,” and “from a spreadsheet.” These can mean a number of different things and you’ll need to be a bit more specific before you’re likely to get much help.
Generally though, no, you can’t copy images that are embedded in a spreadsheet to display on your WordPress site. What you can do is write an HTML <img src="…" /> element in your spreadsheet that references some publicly-accessible image file, and then have the spreadsheet parse your sheet as though it were HTML to make the remotely-referenced image appear on your page. For that, see the How to enable HTML in the Inline Google Spreadsheet Viewer post, a sticky in this forum.
