Devin McRae, an entertainment lawyer, said that the victim could be in line for a $1 million claim for damages.
"It could go into the seven figures, it would seem," he told website The Wrap. "I think the victim would have a very solid case."
He said she could sue for invasion of privacy and intentional infliction of emotional distress. She could also potentially sue under a "revenge porn" statute, which forbids the intentional distribution of an image of a person without that person's consent, if the distributor of the image knew that the subject had a "reasonable expectation that the material would remain private" and if the image "exposes an intimate body part of the other person".
Dissemination of private images carries a punishment of up to six months behind bars.
The LAPD is looking to make an example out of Mathers, and the LA city attorney has already launched a review of the case and will announce its decision soon, according to gossip site TMZ.
Mathers, 29, claimed that she posted the image by mistake, and issued an apology.
"I just want to acknowledge a photo that I accidentally posted," she said. "It was absolutely wrong and not what I meant to do. I chose to do what I do for a living because I love the female body and I know body shaming is wrong, that's not what I'm about and this is not the type of person I am.
"The photo was taken as part of a personal conversation with a girlfriend and because I am new to Snapchat I really didn't realise I had posted it, and that was a huge mistake.
"I know I have upset a lot of people out there but please, please believe me this when I say this: this is not the type of person that I am.
"I have never done this before and I will never do this again, you have my word."
Her lawyer Tom Mesereau, who helped Michael Jackson beat child molestation charges in 2005, said he hoped that reports the woman was intending to press charges were false.
"I hope the rumours are not true," he said.
"Dani Mathers never tried to hurt anyone at any time and certainly never tried to break the law."
