Week 3 Sharing images

Hi, have just read the above topic and have found Flickr an interesting site, full of many pictures that I will be able to use in my work environment. The image I have placed is of the Sydney Art Gallery which is not far from the Mitchell Library in Sydney. I copied the image from Flickr, saved it in 'my pictures' and inserted the image in this post.
Only one failing with this is that the original image is rather small and when I try to enlarge it the image becomes very pixelated. So does that mean that the person who has uploaded their image would like us to just look at it and not download it. Tomorrow is the last day of term so I will take some pics of school, create a Flickr account and upload them and see how I go.

Cheers  Eileen
