I have noticed some odd narrow box outlines around some of the graphics on mumsnet
They are not very obvious and not there all the time but because I am a perfectionist they are annoying me so I thought I'd point them out
In my brief acquaintance with web designing I think they were something to do with the slices having the wrong settings or a margin or something but don't actually know what I'm talking about can't really remember
I am using Firefox on a Mac
here are some pics
annoying box one
annoying box two
