A google image search lists 35,350 images of Alexander. It would seem unnecessary to stockpile them all here when they are so easily available elsewhere. They range from the ridiculous to the sublime. For more images than you want, Google Alexander The Great on an image search; you will have all you could wish for. Originals, not already on the web would be very welcome indeed. This one by Flagstaff photographer, C Zach Hidalgo is interesting. It is on his photoblog. If you wanted to publish it you could contact him. I would caution though to make certain he has a legal model's release as well as his permission to publish. The model has rights as well. I would think it safe to use any of the ancient sculptures in museums as you wish but it would be wise to include the name of the museum in which it is kept. Remember that the photograph of the object is an intellectual property as well as the work of art so the more generic the shot and lighting, the better. I generally put the photo on Photoshop and change the lighting, the general color tones, the background, and the proportions of the image to the point where no one could say,"I took that picture." Museums are now seeking to copyright all images published of objects which they own. The Louvre is a leading example of this and Bill Gates is going around the world buying up rights to old masterpieces in order to keep others from using them ( very much like Microsoft, isn't it?) Unless you are planning to use an image commercially, you are rather safe. Using them here in a closed group like AW should pose no problems whatsoever. If anyone has proprietorship, they are required to contact you and ask you not to use their image before initiating legal action. You can just take it down and the whole thing is over and done with. There is a lot of ungraceful greed in the intellectual properties world just as in every other world and you should use caution, but don't stop using images altogether. In general you are rather safe here on AW, but remember that what we do here often winds up on general search engines throughout the web. AW posts are all over Google. When doing research, I often run into my own work in a search. Sometimes it is even a help.
