Dear Pat Your problem with numbering lies with the computer. Being "digital" it is rather thick and can only count up to one in binary. Either 0 or 1 for off and on. When the computer sees your files numbered in base ten in the first instant it will keep your files in the order they are saved but on the second saving it will re-order them as 1, 10, 11, 2, 3 etc. A simple way round this is to prefix your file names with a zero ie: 01, 02, 03 etc. or if you are likely to go beyond 100 use two zero's etc. I hope that helps - don't blame Barbara !

When I gave the CD to my sister to put on her computer the pictures came out in all sorts of order. Can you explain why and have I done something wrong? And how can I stop it happening again. Someone has mentioned "Finalising the disc" What is this and how do I do it? Hoping someone can help me Thanks Pat Baker
