The original copyright holder retains all rights regardless of how the photo may be altered. Unlike a recipe, where lists of ingredients can't be copyrighted, photos are copyrighted works of art and can't be used without the permission of the copyright holder. That's not to say that this doesn't happen all the time, but if the copyright holder wanted to make an issue of this use, they'd have an iron clad case.
Not to get too pedantic/semantic, but use of a copyrighted image is not always a crime, as there are certain conditions that must be met for the criminal provisions of the U.S. copyright code to be applicable. Many unauthorized uses of images will be against the law in terms of creating civil liability, but will not necessarily meet the criteria for criminal liability. Also, copyrighted works can be used without the permission of the owner in the case of "fair use" that meets certain criteria (although these are more amorphous than the conditions for criminal liability, as they are applied in more of a multi-factor balancing test), although much of what's done on the internet with others' photos (posting of others' photos in whole without permission) probably would not qualify as fair uses. Certain websites such as Flickr allow users to assign default permissions to their photos (e.g., anyone can use, so long as there is attribution and so long as it is for non-commercial purposes), which cuts down on the transaction costs of getting permissions from copyright holders.
