I would use a second form with a larger image control.
In the Click event of a button or the Double Click event of the image control you could set the picture property of the large image equal to the picture property of the small image (depending on your setup)

You could say something like:
Forms!FormName!imgCtrl.Picture = imgCtrl.Picture

I second Kevin's idea, and that was how I did it in my movie collection database.  See picture below.

Thank you both for your input. I did as you suggested and got the large image to appear; however, as I move between records and click on the current record image I get the same image. Need more help. Can you provide a sample vba code?

sounds like a requery may be needed.  try one of the following Requery in Place, requery subform and this last one is nice to inform you what may be the best option requery vs refresh

In the Large Image form I set the following properties:

Navigation Buttons - No
Record Selectors - No
Scroll Bars - Neither
Min Max Buttons - None
Modal - Yes

The forms with the code I used are shown in the screenshot below.

Kevin, I tried your code and still no success. Can you review my code to determine what I may be doing wrong?

Below is the VBA code associated with the small image on my Vehicle Form:

Private Sub VehiclePictureImage_DblClick(Cancel As Integer)

    Dim lastBS As Long, imageName As String

    lastBS = InStrRev(VehiclePicture, "\")
    imageName = Right(VehiclePicture, Len(VehiclePicture) - lastBS)
    
    DoCmd.OpenForm "LargeImageF"
    Forms!LargeImageF!imgLargeImage.Picture = VehiclePicture
    Forms!LargeImageF.Caption = "Image: " & imageName
    
End Sub

-----------------------------------------------------------------------------------

VehiclePictureImage is the name of my image control on the form.

When I double-click the small image on my VehicleF, I am getting the following error:  Compile error: Variable not defined

-----------------------------------------------------------------------------------

I made the changes you suggested on my LargeImageF and when opened manually I am able to see the images of my 4 vehicles. I temporarily enable the navigation button and can cycle through my vehicle pics just fine.

The connected the LargeImage form to the same Record Source as my main form (VehicleT) and I named the Image Control the same as the small image (VehiclePictureImage). Should it name be different?

Thank you in advance for your continued assistance.
