Including a photograph when advertising your horse will increase the likelihood of you making a quick sale because potential buyers will have decided that this is the type of horse they are interested in buying, before making that all important call.
any old picture of your horse won't do the trick. You need to consider what
impression you want the buyer to get and then choose an appropriate picture,
which is clear and sharp.
your horse is being advertised as a show jumper, for example, then the picture
should show the horse's technique over a fence, while a photo of a dressage
horse should show its paces. Equally, a child's first pony should be pictured
being ridden by a small child.
side-on shot showing the horse's conformation will give a good view of the
animal, especially if it is a youngster or show horse, but make sure the
background is not too dark or "busy".
a pretty headshot may be eye catching, it can suggest that the rest of the horse
is being hidden for a reason, which may put off a potential buyer.
weather always helps a picture look good, but make sure the sun is behind the
photographer, to avoid shadows appearing across the horse. Don't be too
ambitious with the type of picture you take. A clean, sharp, still image is
better than a blurred, moving one.
can use the services of a professional photographer, with their permission, but
photographers must be credited in any advertisement in which their work is used.
