Combine Clip Art Images into One Image

oliviamarie You could take a Screen shot of the combined image.  In fact, I strongly recommend compiling the image in a separate document and then taking a screen shot and inserting that into your document with it's layout set to In-line with Text as your document will then the far less susceptible to becoming corrupted with miss-matched xml tag errors.  You should retain the document(s) in which you compiled the images in case you later need to make adjustments to them.

While you can take Screenshots via the Screenshot facility in the Illustrations section of the Insert tab of the ribbon

I can highly recommend Snagit from www.techsmith.com as a more capable utility than the above Screenshot facility.
