Help with VB and MS Access Database?

Is there any particular way to have a picture box that cycles through images based on whatever item is currently being selected in the form?

For example, I have a form that is populated through various textboxes. Each textbox contains information about a product from a store (name, price, item no, category etc etc). All the information is linked to a MS Access database.

On this form, I have two buttons that cycle through each product (forwards and backwards). Is there anyway that I can make the picturebox change in accordance with the item being selected?

I have the pictures currently in a separate folder from the Access DB folder.

If the form is within the Database the Data is located then :

Public Sub FieldName_AfterUpdate()
If FieldContainingDescription = "ItemName" Then
FieldContainingPicture.ControlSource = FieldContainingDescription.Column(ColumnNumber)
End If
End Sub
or
Public Sub FieldName_AfterUpdate()
If FieldContainingDescription = "ItemName" Then
FieldContainingPicture.ControlSource = Dlookup("FieldContainingPicture","Table","DesrciptionName=" & FieldContainingDescription)
End If
End Sub

Have not as yet tried External links to Databases, but note that Excel and Outlook do work.
