I have access 2007 form which contains some of the lists and one image that I used to re-size using on-click event but when it gets re-sized it becomes behind my lists even if I set the position property to "bring to front" and "send to back" for my lists and by the way it works well with text fields ; any suggestion ?
I haven't tried Access 2013, but up until Access 2010 Listboxes and a few other elements do not support z-order positioning (behind or in front of other controls). They are always on top.
In 2010 I use Layouts to expand / shrink the form as elements grow. Another thing you could try is to put the image in a new form, and set the window border, title, etc to nothing. Then you could open the image (as a form) and position it using DoCmd.MoveSize
