I think as far a quality is concerned it is a level playing field. There are great and poor images in both markets. What people are saying though (I feel) is that if it is an image that isn't going to net a bucket of sales, there is no point in having it in micro, where, you won't make money UNLESS it has buckets of sales.
If the image is 'special' in some way, and is limited in it's uses, you should put it in macro, or midstock so that when the 1, or 10 people who need such an image find it, you will be paid accordingly.
awesome, thx tyler. i think you've answered my question. it's somethng that's been ununanswered for so long. now i get it. if it 's not a generic type of image, best to give it to midstock or macro.
clearer now! cheers leaf !
