Win 7 Pro, SP1.
I have set Irfanview on my computer as the default viewer for JPEG photos. The JPEG’s display with an Irfanview icon (in List or Details mode), and open in Irfanview when I double-click the icon.
However, when I connect my camera to my computer via the USB cable, navigate to the camera folder with my photos, and double-click on a photo, it opens in Windows Photo Viewer (although the icons of the photos in the camera still show as Irfanview icons in when viewed in List or Details mode). Why is this happening, and how can I stop it? It’s interesting to note that if I right-click the photo and choose Open from the menu, the photo will open in Irfanview.
