Back in the day, I used Imagevenue. Its TOU doesn't specifically ban NSFW images (just the standard warning about child pornography), so I think that they still allow it. Another route is to upload them to Hentai-Foundry (SL has an account there). I cannot link it from here, but it should be pretty easy to find it on Google.
