I want to change the picture size that is displayed on the main tab. Do I just adjust the Height and Width? What about the Left and Top dimensions and the Index? They are currently at the default of H=0.960, W=0.960. I'd like them to be something like 240 pixels by 240. Also do I have to scan them at that size, or will the programme auto-scale them for display?

The Left and Top are the positions on the screen. so by changing this value you are changing the position of where the picture shows. The index is the relative array element number of the picture. Remember that counting in computers start at 0. so if you look at the picture tab, you'll see something like 15 different images that it can store (0-14). By changing the index number of 1 it will show the 2nd picture (which may be blank), index of 2 shows the third saved picture, etc. Commonly you'll want 0 for the 1st chip and 1 for the back (or 2nd chip).

In the case of roulettes I have been putting a whole table at 1 record. So there are 6-8 attached scans (depend on the casino) and picture 0 is the first, pic 1 is the second, etc. But i only show 2 pics on the main screen.

The program will auto-scale them, then right click on the picture and select Magnify. That will pop-up another window showing the full size (which you can resize to zoom more).

I'll let someone else talk about the rest of the stuff.
