Thanks Steven,

I followed all your instructions and have validated each page now, but unfortunately it's still not made a difference to the glitching.

Changing the width of the gallery to 100% causes this -

It doesn't happen on the pages that don't include a simpleviewer gallery, so it must be something to do with that but I'm really struggling to find what it might be!

Thankyou for your help!

Hi guys,

I built my website using slices and dreamweaver - embedding simpleviewer pro in a space in the middle of each gallery page.
Everything looks great except when switching between navigation pages the slices re-jumble themselves.  Could this be to do with the sizing of the gallery whilst it's loading? Any suggestions?
