Incuding a picture in the tab order of a protected worksheet.
 

I have a protected worksheet with four cells unprotected and a picture in it.
I want the user to be able to press the tab key to move around the the four
cells and then the focus to move onto the picture (which is a hyperlink to
the next area of the workbook). I want the user to be able to press enter on
the keyboard so the hyperlink then works.
Everything currently works fine if the user is using a mouse to click on the
picture after completing the information in the four cells, but I want the
worksheet to work for users who only use a keyboard too.
Please can someone help.
Thank you.
