I'd download Firefox browser and check that the pages load correctly and the images are ok. Always worth having two browsers for backup with any browser problems. If these pages and images load OK in FF then you need to re-set IE10. In IE10 click on the cog icon top right. Select 'Internet Options',then the 'Advanced' tab, near the bottom select the 'reset' tab. This will revert IE10 to default. All your favourites will be retained but your add-ons will need to be re-enabled. I'd do this one at a time and check the browser is working OK. If you use 'speckie' as a spellchecker then that add-on will need to be reinstalled.
