thanks for your two links. I have a plain PHP Scrip working which can 
extract the EXIF Data using the PHP EXIF library but for that (and also 
resize on upload - btw. thanks Carsten for your answer, good idea! ) I 
need the "original" image file. But Flow is working with the resource 
objects and afaik the original image files are not stored (persisted).

So, i need to know what happend to the images. Are the EXIF datas still 
there or do i have to do sth like:

Client: - Check valid file Type
-> upload to Server as plain file with no resource object convertion
Server: - check for valid file
	- extract EXIF Data
	- if needed: do resize
	- persist image as rsource object and EXIF data also
	- delete original file because not needed anymore

What do you Flow Cracks think? :)

Greetings,
Jan
