Finally found my own answer:
Select the Excel object you want to save as an image using your mouse. If you want to save a chart, click on the outer edge of the area surrounding the chart. There will be little black squares at intervals around the chart, showing you it is active and selected. If you want to save a range of cells or any other object as an image, drag your mouse over the area you want to save.
In Excel 2003, press and hold the Shift key. While holding it, click Edit on the toolbar. You will notice that the Copy option on the Edit toolbar has become Copy Picture. Click on it and the Copy Picture dialog box will appear.
In Excel 2007, the steps are a bit different. Go to the Home tab of the ribbon and click the Paste dropdown arrow. Point to As Picture and then choose Copy as Picture for the Copy Picture dialog box to open.
Under Appearance, choose As Shown on Screen. Under Format, choose Picture. Click OK. Your Excel object is now saved as an image to your clipboard. If you want to paste it directly into an email, Word document, PowerPoint slide or other location, just click on that location, right click and choose Paste.
If you wish to save the object as an image to use at a later time or several times in the future, open Paint or a similar application, paste the image and save it as a .jpg or other image file format.
