44076 Two dozen generic web images

I need two dozen generic images created. Must be original. 12 (horizontal) images size approx 600x125 12 (vertical) images size approx 125x250 These are generic images, the first set (horizontal) are 'headers' for webpages. The second set (vertical) are 'pointers' (they go next to an advert and bring attention to the ad). I have provided as an attachment, two samples (one sample of each kind) for you to look at and mimic.
