Well, I am actually making a photo database, the user keys in the path of the folder he wants to link to the database in a field with a text data type. The field is called "Photo Location". Then I put an unbound image frame and used Photo Location as its control source.
Then I realised the only way for the user to go to the photo is to copy and paste the path to Windows Explorer, which does consume time. So I was thinking of a hyperlink to deliver him to the folder right away. Which lead me to have a field "Photo Link" with a hyperlink data type, but I can't get it to have equal data as Photo Location since having the user to type it twice does sound troublesome.
