To locate 'DSC_0005.jpg', you should be aware of its location once you connect your camera or SD card. An embedded name or title won't show up in a search unless the file has been renamed. Considering the dimensions of the image, it may be too large for Poser. For a background photo, resizing for a window render isn't possible. Instead, you should place the photo on a flat plane and position it behind the window prop.
