this is an issue that I was hearing about these days, the thing which is called (stock photography) and stock photo websites….
first of all, one of the university people I know was building the university portal, and he needed some pictures to put in the portal, but he didn’t have a photographer, so many people might do a mistake and take the pictures from the internet and then post in online without taking any permission, even if the person mentioned the website, that is not right.
1: the website might bough that picture for a 1 time use, so it is owned by the website.
2: maybe the picture was been taken by a special photographer for the source that the picture was found, and that photographer don’t want anyone else to use the photo, even if the credit was given
so if you you want to put some pictures in your website, and you are not, or someone you know is a photographer who owns some pictures, THEN YOU HAVE TO BUY THE PICTURE ONLINE, and that will make you own the picture, and use it in a proper way.
search (stock photos) (photos bank) (buy online photos) on any search engine, and you’ll find a lot of such websites which provides you with a lot of pictures, with a variety of prices. (from 1.5$ to 10,000$) but most of them are cheap and has very great quality pictures.
