I see you are registered in Bulgaria.
Do you normally search on ebay.com, or another site?
When you say "bottom half", does that mean that you do see images at the top of the search results? If so, try restarting your device.
Do images appear if you use a different browser, a different device or a different network connection?
Do images appear if use another site such as ebay.ca, ebay.co.uk or ebay.com.au?
