This is just how I've been doing it on my PC...
1. Make character
2. Click camera icon, in upper right corner
3. Use "Snipping Tool" to take a screen capture of character
4. Save said screen capture to computer (File + Save As)
5. Upload image as a comment using the image icon on the far right
6. (Optional) Click the now uploaded image to give it a name and add any comments that you'd like
7. Post your character for us to see and love! ❤❤❤
