I find attaching existing images through uploadField very annoying. I had to attach already uploaded thumbs from shutterstock to pages. Everything always went smoothly, when I uploaded image through field - but it's extremely difficult to search from many images in media dialog. There is no search function (I have to type whole name to get results), and thumbs are so small that one can hardly see anything.
Does anyone faced this problem? Is thare an easy way to change thumbs size, number of displayed files per page and to implement working search function?
