Image CSS border bug?

I’m doing a website where i have to display multiple images. In some of these images, a white (and very annoying) border is appearing, especially when the window browser is full sized. (all images have no border at all)

i tried to remove, but couldn’t. Any suggestions?

Without seeing your code, we can’t really help at all. From a photo of part of a screen, my best guess is that image actually has a white strip in it from a sloppy crop job.

Another guess: You could try setting your images to display:block. Depending on the other code you have, this could break your layout though.
