Image Protection

Do you post images on the internet? Do you post them for anyone else to freely copy, use and distribute? If not, how do you protect the images and/or prove they are really yours? Adding a digital copyright or watermark to images before you post them is one way to help identify them. In some cases the watermark can act as a digital ID tag so you can search the web to see who else might be using the image.

Probably not a big issue if all you are posting is grainy snaps of the latest dinner program. However, I know of at least one instance where one of my images was added to a photo index. I also wouldn't be surprised if someone had downloaded a picture of me to make one of those fake celebrity-head-on-a-different-body pictures. (I suspect it's hard to tell if it's really me or Arnold.)

Soooooo if you are going to post an image that someone might want to 'borrow' here are some resources:

This one for all of you engineers. Great introduction and summary... but just a little bit technical in the middle. http://www.cs.unr.edu/~rakhi/reportwm.html

Not an exhaustive or comprehensive search on the subject, but might help get you started.

Front Page

A few tips on how to make your web site show up on search engines. NO! do not pay the listing service. They don't do any more than you can do yourself in a few minutes, free.

A few interesting tricks in Front Page. 

• Global find and replace. Change the president's name everywhere that it appears. Works in Front Page 2000. I use this one a lot to fix links that have changed, as well as names, addresses and phone number.
• Insert a web page inside another. A great way to handle a header or footer which must be inserted in everything. You only have to update one place and they all are fixed. I keep forgetting about this trick... but no more!
• Check all of the links to make sure they are working, find the broken ones and step through updates and corrections. This function saves me lots of time!
