When caching a book from online source, the pages are saved as pictures.
Normally that works very well with Mozilla cache view. And the pictures are numbered and correctly sorted.
For the first time, that didn't work well, because the cached pictures were not sorted correctly and were numbered in a chaotic way.
Problem:
When I load the pictures to Finereader, the pages are not sorted correctly.
So, my question is:
How to sort the pictures automatically, because sorting the pictures manually is a hard job, when you have hundreds of pages to sort.
Can any program help to sort the pictures, so that the pages are in the right order?

Sorry that I ask my question here. But I do not know where else?
