The fliptest.mdb database link in the last post was created in 2007 and saved as 2003 i don't believe you said what version you were using. Also this happens very quickly on my computer i not sure if it will be so on yours.
Directions for testing
Download or open the database
Open the single form
Left click or tab to the image in the field F3
Press f
The image will open in the editor flip then close the editor
If you need a different orientation then press f again it will move around in 90 deg intervals
also if your images are not OLE objects i would advise you to make them so if there is no risk of the database becomming larger then the 2g limit.
OLE linked images have other advantages such as when printing forms the correct image will print for each record.
