nopCommerce would be more usable if all searched products could be viewed without paging. Lazily loading the product images would facilitate this capability. The reason for paging is because of mainly two things: keeping items on screen or performance. Perfomance issues are usually related to image loading, however with lazy loading images this issue can be overcome. Below is a good jquery plugin for lazily loading images that are not in view yet. This would make searching the store similar to viewing Bing Images where you can scroll indefinitely without the need to page or extra effort clicks by the customer.
