Description
i am using opencv 2.4.0 with visual studio 2008. i have used a simple sample code to test cv::imread and it doesn't work. i have tried most online solutions - from separating debug and release libraries and .dll files, putting the image in the folder with the executable, to specifying the directory of the image - but it still doens't work. i even reinstalled opencv at one point.
however, cvLoadImage works but produces a window with an error in the image window name in debug mode and the release mode produces two windows instead of one and with errors in window names as well.
i have tested this with images with different file extensions.
please help!

You should provide both sample code and input images. This is not user group, so if we'll not be able to reproduce this issue, we'll close this ticket.

We have Introduction tutorial that shows imread functionality. See source:trunk/opencv/samples/cpp/tutorial_code/introduction/display_image/display_image.cpp. for source codes. This code does the same thing and works well.
