IKSlideShow problem with NSImage

Hi,

I'm trying to fill a IKSlideShow with NSImages.

In the slideshowItemAtIndex callback I return the NSImage I made. NSLog
shows that:

06.11.07 03:28:07 My Application.debug[91499] result NSImage 0x1eae30
Size={2288, 1712} Reps=(
    NSCachedImageRep 0x127fb0 Size={2288, 1712}
ColorSpace=NSCalibratedRGBColorSpace BPS=8 Pixels=2288x1712 Alpha=YES
)

but IKSlideShow will show:

06.11.07 03:28:07 My Application.debug[91499] could not load thumbnail
for: NSImage 0x1eae30 Size={2288, 1712} Reps=(
    NSCachedImageRep 0x127fb0 Size={2288, 1712}
ColorSpace=NSCalibratedRGBColorSpace BPS=8 Pixels=2288x1712 Alpha=YES
)

This NSImage is memory based. Is that a problem?
Does someone has an idea?

Doing files (NSURL) and pdfs (PDFPage) does work.

CGImageRef does also not work with this message:

06.11.07 03:13:58 My Application.debug[85917] could not load thumbnail
for: <NSCFType: 0x113f20>
