why image not loaded
I load it by cvLoadImage and chek pointer after that. If it's NULL, image not loaded. But I need to know why ( bad format, file or path not found, e.g. ). How can I do this ?

Thanks for answer !
I have no error, at the wrong load (check NULL pointer after cvLoadImage ) I know, that something went not so and print "ERROR", but I don't know why. I need to know why image not loaded.
Use IplImage because further I use cvCvtColor and cvCvtPixToPlane which don't work with mat... ou, try to do with mat.data and it works)
However, the question in other :) How to understand the reason for which the photo wasn't loaded?
You not so understood me :(( I write the program for processing of a large number of a photo, at the wrong loading to the log is written "ERROR" , but it is necessary that there was also a cause of error, like "ERROR : WRONG PATH" or "ERROR : BAD FORMAT ". Can I do this using OpenCV ?
