Just made a new lightbox..STEEL.
If you have any images that are of steel your more than welcome to site mail me at istock with the file number and i shall present your image for inspection before the committee.
Now i make lightboxes to showcase my work and not for the benifit of the istock community of which i am sure was the intention when they were formed.
In saying that i always add images  to my public lightboxes when asked by other members.
Alot of members search out lightboxes for their files and feel quite chuffed if their files are in several lightboxes.
I personally do not follow this course of exposure for my work within istockphoto as i feel keywording my files correctly will attain sales.
