We have no limits on how much you can upload. However, if we detect abuse we'll let you know.
Yes. 8MB is the maximum file size. We monitor the need and if needed this can be changed without notice.

JPG, PNG, BMP and GIF
On image upload you can select the private "lock" symbol. You can also create a private album and upload images directly to it. Another option is to make your profile completely private in your profile settings. Check "Make my profile and identity totally private" and save changes.
Yes. But only if it's marked as "not family safe" (NSFW). Our moderators are monitoring this closely and if abused we're banning based on IP and deleting the relevant images.
Why should everything be about money? We pride ourselves in the product we are offering! Giving is better than recieving.
