Does Windows Explorer allow previewing the large 13G Tiff file or is just a tiff file icon shown in explorer? Does the tiff file have more that 1 image? If there is no thumbnail of the tiff image itself and the tiff file only contains one frame, the file may be corrupt or imageen is having difficulty opening the large tiff file.

I suggest you post a link so that Nigel can download the 13G Tiff file.

Maybe Nigel can answer why the thumbnail is black.

Also with large TIFF files I suggest you compile the application as Win32 to provide ImageEn with additional memory and to add the 64-bit dill to the exe folder. You should also call AttachedBitmap.Free I believe.
