While the image choices are great and so is the quality, BUT, and a very big but - I purchased credits on Friday. Now it is Tuesday and while my money was taken quickly, my account at istock shows zero cedits. I have written to them every day, with absolutely zero response. That is not bad service - that is absolutely zero service which says we want your money, but do not care a hoot about our customers. BAD, BAD, BAD.
