i made a new folder of images... 340 images... and the first time i got another 0kb image, 2nd time i got a "runtime error" and the program terminated.
Is your original image located on the hard disk (if on a read only media then you can't have any image)?
In other words are you saving the mosaic to a folder on C:\ or another hard disk?
Are you using the latest beta version?
What is your operating system? How much memory RAM do you have?
What is the final status message? Mosaic completed?
What do you read in the Mosaic Information Area?
Do you have enough space on the hard disk left where you save the mosaic?
Do you see the preview image in the main window?
