admin-arrange for the picture/photo shares

I agree with you

If Admn provide this facility at fourm then it will be more easy to share photographs with others.

Approval powers for such things have already with them

You can very well share the photos through shared files section, you also have the section for sharing videos...

I know it is possible but It will be better if it is differentited form files,vedios,etc.

As with photo sharing you may be able to view photo in large size,noraml size,small size,in special effects,download,pass comments etc..

Currently you have to download the file to view the photo and it takes some time and also consumes some KB /MB in download.
