Dear all, When my images are presented, There is a black border appears around the image. Is there a way to remove them? Also, some images are presented in very low resolution. Any suggestion? [image]

haha ! I guess I found an easier way. I created a rectangular white transparent polygon following the image position and size. Most of the images have no lines! Thanks for your answers. [image]
