Hi Kari
I took a quick look at this FAQ suggests you can save as jpg.
http://www.novadevelopment.com/Support/Faq/sfw.aspx
scroll down to under Problems.
You can also save to pdf.
I am guessing but when you choose save and teh save window opens there should be a drop down box. You need to change the file type in teh drop down box to jpg.
You also need to be careful to save your page at the print resolution as it says its defaulst to a low resolution.
Check either the link or your help files for more info
