Sample image, JP2 format

Any JPEG2000 image which uses 2x2 subsampling will cause a crash when
decoding it with WebKitGTK/WPE. I am attaching a sample image which
can be used to reproduce the issue, created with:

  % opj_compress -i haisuli.png -o haisuli.jp2 -s 2,2

(The “opj_compress” tool is par of the OpenJPEG package.)
