It shows as safe, but look at the comments at the McAfee site adviser page:
A few years ago, I purchased a Photobucket account and uploaded all of my precious photos of my children from birth to age 10. That's ten years of photos. When it came time to renew, I was not able to renew right away. Flickr, Picasa, and SmugMug- and every other photo archiving service keeps your photos but just does not give you access to them unless you pay your fee. Photobucket deleted every one of my photos! They are gone forever. I am a huge tough guy. I cried. When I contacted photobucket, they did not get back to me until I emailed them numerous times. They were snide and unhelpful. Tough shit they basically said. I DEEPLY REGRET USING THIS TERRIBLE SERVICE. I would rather have been robbed of everything I own than have those photos deleted! I now use SmugMug. I had a question recently and they got back to me within three hours- on a weekend! They never delete your photos. Neither does Flickr. Use anything BUT Photobucket.
It annoys me that I have to go to the site to upload, unlike services like Dropbox, which is a lot easier.
Not only is it slow and lots of downtime, but has also no secure encrypted connections!
(Can't connect via "https://photobucket.com", which pretty much means it doesn't support / allow it.)
This is a serious error that could be easily fixed, specially when you've got personal images for only close loved ones to see, not the entire internet.
