I had the same problem and it was driving me nuts. I think it's a bug.
Below is how i worked-around it.
Do what you do now by calling insertImage(...).
This will insert the image into the data-base; however, thumbnails are
not correctly generated and the SIZE attribute is 0 (your problem that
you see).
Execute a query, and use the cursor to get the physical file-path (use
the ImageColumns.DATA).
Using the physical file-path, use the MediaScanner
(MediaScannerConnection) to scan your newly inserted image.
After the MediaScanner has finished, querying your image on
ImageColumns.SIZE (and other attributes) should work correctly.
I suggest to do this in a seperate worker-thread... it is kinda-slow.
