Yes, that photo is not of real spiders. Red-back spiders are often found in outdoor toilets, back-yard sheds and other, similar places. If you have a garden shed, say, with gloves in it...before you put the gloves on you have to stamp on them just in case there are spiders inside.
Most often though, you might see harmless house spiders (Google "huntsman spider") which, while large and scary, can't bite you.
