Image plane

I hava problem with some JPG images, in maya I make a plane, apply a lambert material, in the color box I apply a image like color, but the image in the plane appears inclined, not all JPG images appears like that and I don´t know whysome appears correctly am others not, and I must to change the hardware texture attribute to fix this, but the image in the plane losts quality, how can I do to don´t change this attribute and these image appears correct with the default value in the hardware texture attribute?

hello

mostly a reason for and image plane inclining is that you setup the image plane in orthoview and do not switch back to perspective view when working. your setup say front view in ortho and don't switch, then rotate view and now your image plane is incorrect. is that your problem
