        with Image.new("RGBA", im.size) as background:
            rgb_avatar = im.convert("RGBA")
            with Image.new("L", im.size, 0) as mask:
                mask_draw = ImageDraw.Draw(mask)
                mask_draw.ellipse([(0, 0), im.size], fill=255)
                background.paste(rgb_avatar, (0, 0), mask=mask)
        return background

roundedAvatar = rounded_avatar(memberavatar)
roundedAvatar = roundedAvatar.resize((311, 311), Image.ANTIALIAS)
roundedAvatar.save('cards/roundedAva.png')
r = Image.open('cards/roundedAva.png').convert('RGBA')
im_a.paste(r, (92, 193))
