You'd need to convert the pictures to 72dpi and then upload to the webpage, there is no way a browser can do it unless there is a plugin I'm not aware of.
Use XnView's "Batch Convert -> Set DPI" to convert the TIFF 100dpi to JPG 72dpi images.
Thanks

What's the point of changing DPI of an image??? Really?

The only time DPI takes effect is when you print the image. The people downloading the pics can simply resize the images themselves when they go to print them if they want a smaller image. They can either resize it in the print dialog or open it in any image viewer/editor and reduce (or increase) the DPI themselves.
If you're trying to create smaller files for web viewing, then you need to reduce the dimensions of the image (ie take it from 500x500 to 300x300), not the DPI.

from thread
http://newsgroup.xnview.com/viewtopic.php?p=24734 :
The reason is that a lot of magazines - Newspapers - and webdesigners are using the pictures, thats the reason to why i have my photos in 72, 150 and 300 dpi
As I said, they can easily change the DPI themselves. A 3 DPI image and a 3,000 DPI image are identical when viewed on a computer, so as long as they change the DPI before they print it, it makes no difference.
