It depends on how many photos are on the product page. If it has enough photos and something to help you judge the size, then they probably aren't needed on the review. But sometimes you get an info page that has only a couple of photos, doesn't show a key feature, or
lingerie where they don't show what it looks like from behind. In that case, if you have the ability to add photos, then it will be a huge help to buyers.
But one thing that a photo can do is show that you actually have the item in question, and that it isn't an invented or plagiarized review. That's why
Real Sex Toy Reviews will only accept submissions of reviews with photos in it. Though people who are here and active in the community aren't likely to be fake reviewers, most of the people reading the review and thinking of purchasing the item don't know us or visit the forums. If they see a review with even one photo of the actual item, it's going to give them a little more confidence that the review is genuine and not an astroturfed sales pitch.
