So let me get this straight. There's an encrypted transaction in that picture? And that transaction has txid 987d303ac8a32982ae945957a9bf4cc1977b8dcf4b993fe2663ef9cea52d6848.

So that's steganography. I ran stegdetect on it and it gave me a false positive for an ancient program called jphide that doesn't use f5. I ran it on another transaction with a different image and stegdetect didn't detect anything. So the best steganography detection software is completely undependable for sonic vortex because it gives false positives and false negatives for sonicvortex, but no true positives. My guess is that it could do better but transactions are very small compared to the image.
