Hi, ditto with the above comments. Your front page has a bit of side scroll due to not starting the site from the far left of the page & using one of the images at 1008px wide
(

The images will load ok as there is only 1 per page, but many are at 350kb plus & could have been nearer 50/60 kb for this size image.
