I am having the same issues. My images are 500 x 216, the short code is as follows:
[promoslider width=’500px’]
Also tried:
[promoslider width=’500px’ height=’216px’]
Both result in a dirty grey border under the images.
First question. WHy THE HELL USE A GREY UJNDERCOLOR? IF THERE WERE NONE THIS WOULD NOT BE A PROBLEMl USE AS TRANSPARENT PNG.
Second questionL Why is this happening at all?
20+ plugins tried for a simple image rotator. All have dispsh*t borders, thumbnails, under colors, arrows, self congratulatory ads and other BS when all i want is a series of images to change, one after the other in one spot. Dear god is that too damn simple for you geniuses?
