Copying pictures to Excel worksheet

I would like to create worksheets of my co-op orders, spring bulbs, perennials, etc. using Excel. I would like to be able to copy pictures from the web into the worksheets next to the name of the plant/bulb/seed so I can see at a glance what it looks like. Is there a simple way to do this? Would it make the file huge?

Thanks in advance to all you wonderful wizards out there in DG land.
