If I've used an asset across multiple pages, then the one it appears first on (first in the order of my sitemap) is where it'll be credited. They are ordered in what I see as logical i.e. up left to down right across the page and within each section of a page.
If you want your asset removing from my site then please email me.
asset name / description = the images proper name or a short decription by me
link = either the whole or part of the link that when clicked on takes you to where I found it
author / extras = the name of the person who I got the image from (not where it might be orinigally from if it's not listed) following BY, or the link to the original item (not the person that made it into the image I used) following SEE ALSO
