WhatsApp group pictures
One picture for each member of the BHD team. The pattern says the department and the colour says the person. The brand pictures are here. Every one is 1080 × 1080, laid out for a circular crop, and checked at 40, 64 and 128 px before it was kept.
Setting one on WhatsApp
Download the PNG, then in WhatsApp open Settings, tap your photo, choose Gallery or Photos, pick the file and confirm without zooming. The art is already positioned for the circle, so any crop you add will eat into the breathing room around the mark.
