How to turn a doc into jpg

I added text onto photos through Preview.
Then I went to Pages and selected Blank Document. I added more text (in text boxes), dragging photos (with text) from Preview and rearranged them all to my liking.
Now how do I turn my document into a jpg so I can pin it on Pinterest?

Take a screen shot of the page. Open that screenshot in Preview, crop to your liking, and save as JPG.

Taking a screenshot won't do the resolution a lot of good but maybe OK for website. You would be better off using a proper graphics editing program such as Photoshop Elements which would do everything you want.Pages is the wrong program.

You can test drive Elements by downloading a 30 day trial from Adobe.

Try clicking Print, then select PDF at the bottom of the Print dialog box, and then Save PDF to Folder as JPEG. Choose your folder and click Continue.

As far as I know, this method will work from any program (Including Pages) since it's built into the OS (I'm on Lion, by the way).

Good luck,
