Hi, there are 3 main reasons why an image may not be showing, this can be in the free gallery, private gallery and your main profile images.
1. You havent consented yet, this can be done here. Remember to update the consent every time you add a new image.
2. They havent been manually approved by Adultwork yet, the estimated time is 12-24hours, so plan ahead. A more streamlined method is being worked out.
3. Your browser cache needs cleared. In most cases, while viewing your profile pressing Control+R will refresh it. If using something other than Windows google how to clear cache.
