Hello Jan, I have a number of Adobe photo editing programs, but the one I most prefer is their Limited Edition, Number 5.0. It is relatively inexpensive, and easy to use. And even though not having all the more powerful features of Adobe's Photoshop, etc., I do not feel limited. Without knowing or being familiar with which software you're using, I really can't tell you what to do. However, when you save a file, select "Save As". That should bring up some form of menu which will allow you to pick a number from 1 to 10. The lower the number, the smaller the file size. Number 3 or 4 is more than enough for the web, and you will see no deterioration in quality. You also can select picture size, and then reduce it from the 14-17 inches that are the out put of your camera to a more useable 5 or 6 inches. You have should the option of doing this in pixels or inches. Here's a link to one of our pages. You can see how quickly the pictures open. http://www.landandseacollection.com/id2.html If you need something further it may be best to take this off-group, Joel Jacobs ----- Original Message ----- From: "Jan Kalivoda"To: Sent: Tuesday, July 20, 2004 4:54 AM Subject: Re: Navigation instruments from Paris, Maskelyne > Hello, Joel, > > thank you for your remark.
