It says You are not True Nudist Certified
What size were the pictures? They must be less than 1mb...
The way to shrink a pic to less than 1 meg is to use a photo editing program (I use Photoshop Elements). Open the file of that pic. Save it with the quality down 1 notch. It probably takes very little reduction in quality. If the result is less than 1 meg, you are in. I don't notice any difference in the pic.
I'm not sure how big they were but I know they weren't very big. I changed them from bitmap to jpeg to make them fit. Would you like to see them? I'll send them to you if you send me an email address. Maybe you can tell me if they are wrong or not.
If you would like, you can upload the pics to your profile and designate them for truenudists only. When you do that only a very limited number of people would be able to see them - certified, paid members only. Then we'll take a look and see if there is any reason why they're not being accepted. We rarely share our email address with anyone.
