There are many ways to capture macro images, from using the macro setting on your camera, to having a dedicated macro lens,
with all the bells and whistles which can be cheap or expensive, depending on your budget and dedication to capturing "that" image.
Budget is adding extension tubes or mini bellows or you can go to ring flash which is more up market.
I have added a couple of links, the one image that eludes me is very well done by a photographer in England, Brian Valentine and his flowers inside a water drop.
He only started outwith basic tools but has built up his gear over time but his images are amazing..
The great thing about macro photography is you only have to go as far as your garden and get some wonderful images
