Hello Jignesh, as a solution you can try this http://amasty.com/extended-order-grid.html extension. It allows you not only display product images on your order grid, but to add any necessary order info to the grid. You can also easily searching and sorting orders by product name, SKU and other attributes.
Moreover, the module enables you display coupon codes, shipping and payment methods on the grid as well.
