links are in one column all touching each other (ie no gaps) however when using
IE the images have a gap between each on does anyone know whats cuasing this

Thanks in advance

Hello,
I think you'll need to paste the code for people to see. Could be any number
of things causing those gaps, but I'm sure you'll have an answer quickly with
all the helpful gurus here once they see your code:-)
Take care.
