well, it's a bit boring operation cause AChat don't support screen capture directly, but here we go….
1 – while in room, turn the camera till you find the right view you want, then press the “Print” button on your keyboard (or “stamp”, depend where you live!). usually it's placed near the “F12” button.
2 – open an image editor program, like Photoshop (paint of windows is good too) and paste the image there. now, you can adjust the pic if necessary, then save it on you HD
3 – login in the AChat main page and, in the right corner of the screen under “Buy A$” you will find “Character picture upload”: hit it and follow the instruction who appear. Be sure you have 99 A$, cause they are needed to upload personal pics.
