You say you import image ID 1018. When it fails it is pure black? Do you mean image ID 1018? Then what does image "ThumbNail" have to do with it?
When setting the imageData, the height and width must match the original. (Strictly, the size of the imageData must fit the product of the height and width.) I usually clear the destination image (put empty into the text of image "ThumbNail") and set the height and width, first. This will reset the alphaData/maskData, too. I also clear before setting the filename property in some situations.
The source image is always fine. It is an 80x60 imported JPG (currently, I've tried other formats.)
Image "Thumbnail" is the target. Basically, the source image is a default state. "Thumbnail" can receive other data placed into it at various times, but gets returned to the default at other times. There are an arbitrary amount of these "thumbnail" images, one per data card. So, just setting the ID to the source is not acceptable, I need an independent copy of the image data there.
I'll try the emptying trick, using the "text of the image." I hadn't gone that route yet.
When you dump in your troubleshooting, be sure and include height/width and formattedHeight/formattedWidth. Also alphaData (and maybe maskData). You can also save the image itself. And you can export the image to whatever form you want, including the human readable PBM.
OK. Reset the dimensions. Got it. I'll try that too. At this point, I'll try anything. And when it works, I won't trust it, because I've had it working flawlessly before... until it doesn't.
