As I upload a picture and as I am filling a little form about my picture i noticed that you can only have copyright only to a user ( which is me) but wouldn't be better if you can write whoever receive the credit? Just a thought.
But as my friend or other websites allowed me to i should be able to unload a image for them right? also if i want to upload let say NASA pic. I just want to write (c)NASA.so that they receive a credit.
i think you could put a comment in the description for such special cases. making it so that you can easily credit and upload other artists would just encourage potentially bad behavior
As someone who uploads NASA images on a regular basis to the space gallery, the best way to do this is to include the credit line specified within your description of the image.
