PIcture Hunting (but fun).

I need you to find me 1440 images - one corresponding to each famous event/person outlined in a spreadsheet I will provide.

Images must satisfy the following criteria and will need to be saved in the following format:

Minimum height and width: 450px x 450px
dpi: 72 or greater
(If the above criteria can't be met, get the best available image, rather than none at all).
Colour, black & white, sepia images etc all fine.
All file formats acceptable.
Note down the URL for each image captured and add it to sheet (most of these will be the URLs already listed on the sheet) .
Each image file name clearly labelled in relation to the cell it refers to.
Single focus point (e.g. a person/object being the focus of the image) if possible.
Make sure the image is relevant/refers directly to the text.

You should be able to create one a minute once you know what you are doing.
