You can't do image decompression in GPGPU because the last step (Huffman coding) is not parallelizable - in fact if any compression is parallelizable it's not compressed enough. But you can do it in dedicated hardware.

Ok, maybe not the arithmetic code (or huffman), but I was thinking you'd at least invert the DCT on GPU.
