Can I remove the black lines in the uploaded example?
Context:
To block out ugly neighbours, I've put some 'cubes' around my block, made them as slim as possible, made the 5 unused edges transparent (so neighbours can't see them blocking views...etc) and then filled the used side of the 'cubes' with images containing transparencies at the top.
I don't think there are black lines at the top of these images. However, black lines appear around the seams of my images, which take away from the overall aesthetics.
I want to somehow remove those black lines - is this possible?
