Description:
------------
It would be nice if the imagecreatefrom*, exif_*, getimagesize, iptcembed, iptcparse functions would not only work with files but also with buffer-variables containing image data.

Then if retrieving binary image data from a database, it would save the overhead of writing and reading this data to plain files for data manipulation.

All functions you have named can handle streams, so the only thing you need to do is using a stream around your buffer stream_register_wrapper(). And there is also imagecreatefromstring() which can handle php strings as buffer. That works because php strings know their length and can store \0 in contrast to c strings.
