Ok I've knows this and used this trick for almost 1-2 years. The reason i use this is because its hard to find the "right" image which can be found easily on istock. I think most of your wont know this so i thought i'd share. If you know this you can just ignore this share. 1) Go to istock photo and select the picture you like. 2) Copy image url of that picture and paste that in Code: http://www.tineye.com/ 3) Tin Eye would find the same images used on other websites in full size without watermark. 4) Save Image and use it for whatever you like. Best part is since these are istock images nobody would think that actually "dint" buy the image. The "popular" images which have had thousands of sales are very easy to find with this method! Hope that helps!
