It's come to my attention that many of these are too big for people to print straight out of their browser. There are a few reasons, and a few things you can do about this.

First, don't forget that most of you can reduce these pictures by going to Page Setup under your file menu and changing 100% to something less. Often if a picture is just a little large, you can reduce it to 90% or 85%. Some are actually long enough to warrant reduction to 50%.

If something looks wider than it is tall, go to Page Setup for that as well, and change the orientation, from tall to wide.

Important Facts:

Most browsers will print all pictures at 72 ppi (pixels per inch), which is (roughly speaking) your monitor's resolution. This is NOT really the ideal resolution for something you're going to print.

When it's possible, it's best to print pictures anywhere from 80 to 200 ppi, depending on the printer you're using.

When I set many of these pictures up, I set them up for 80 ppi. Hence the trouble. :)

You can still get higher resolution, effectively, if you reduce the picture print size in your Page Setup. Let's say you were printing something at 50%. Your effective resolution, instead of 72 ppi, would be 2 times as much, 144 ppi. Inverse proportionality rule applies here. This also works for programs like Quark and Pagemaker, but not programs like Powerpoint (or the other Microsoft products).

BEWARE! ADVANCED MATH TECHNIQUE: You can look at the picture size in pixels (in Netscape it's right there in the title bar) and divide it by the number of inches (wide with the first number, long with the second) to see what percentage you should use in reducing the picture and still keeping as much as possible. The formula is # of pixels divided by 72, then divide the number of inches on your page by the number you got in the first part. You would use the smaller number that you come up with out of the two. Don't forget margins!

Example: Picture is 640x800, your page size after margins is 7.5 inches x 10 inches.

640 / 72 = 8.9, then 7.5 / 8.9 = 84%
800 / 72 = 11.1, then 10 / 11.1 = 90%

Since 84% is the smaller number, you would reduce to 84%.

You should be aware that I have noticed at times browsers will not start printing the picture where it should on the page. Sometimes the top left corner can be a full inch further down and to the right than the margins call for. Very frustrating, so if it happens to you, just take it into account. If you know how to fix this, please tell me.

Those outside the USA: 72 pixels per inch = 29 pixels per centimeter.

If you have questions you can email me.

If you're printing out of Photoshop, you can resize it under Image Size. Just make sure you constrain file size so you don't lose resolution (and detail). (See graphic, that's from Pshop 3, Pshop 5 looks a little different so be careful.)
