IANAL, but if it was taken in a public place (in England) then there is no legal comeback, per se.
However, if the image is published (online or in print) alongside comment or editorial that defames, libels, or otherwise indicates anything personal and unlawful/unsavoury, then the juxtaposition of the image and the text could be problematic, even a mere hint or suggestion is enough.
Images posted for artistic purposes, exhibition, and/or critique wouldn't ordinarily cause such issues.
Submitting images for editorial use or to image libraries is a different kettle of haddock.
