Yes, sometimes it is very difficult to find any images. There were especially problems with the search for threesome images It's good that I found a large database thanks to which I managed to make interesting images of the project.

You can use any of the selected images, or you can copy a link below the image space, but be sure the image is at least 100x100 no higher. Pretty simple.

You should first have your picture as a file, 100x100 pixels or smaller. Any common format will do, but .png and .jpg are easiest to work with. Then you upload the file to an image hosting site - imgur.com is a common choice. To assign the picture to your profile, click "Edit Profile" on your personal page and put the image link in the first text box. For Imgur this is the one that ends (something).(format).

I have a thread on my profile that has at least 8 great avatars you can use
