Is it ok to use image hotspots? Is that the best way to do it in today's world?
I have a picture that needs to be split into 4, and each part must have a link. Do peop开发者_JS百科le still use image hotspots?
I am assuming you are talking about client side image maps.
They are still being used and are part of HTML 4.01 and XHTML 1.1, and also in the current HTML 5 draft.
They are simple to use and are supported by all browsers and as such are a good way to have "hot spots" on a single image. I can't think of a single better alternative (ease of use, browser support, accessibility, being part of the HTML spec) that will give you this functionality.
Whether having such "hot spots" on a single image is advisable (discoverability by the user being the main issue), is a different question.
Using images as links is lame in my opinion; it can hurt accessibility, and depending on the image used, can result in Mystery Meat Navigation, which is lame.
Instead, I'd make that image a background image.
HTML
<div id="image-hotspot">
<a href="#small-planets">Small Planets</a>
<a href="#big-planets">Big Planets</a>
<a href="#the-sun">The Sun</a>
</div>
CSS
#image-hotspot {
background:url(http://onlyfunnyjokes.com/bestoftheweb/wp-uploads/earth_planets_size_comparison.jpg);
height:650px;
width:385px;
}
#image-hotspot a {
display:block;
text-indent:-10000px; /* you could also change the opacity instead*/
/* as a matter of fact I suggest using the opacity technique */
/* the text-indent has caused me troubles in the iPad browser */
height:216px;
}
You might need to use more advanced CSS positioning to make sure those anchor elements <a> are where you need them to be.
Addendum
Here's another example which should seem more relevant:

You can use image maps, the main reason people don't like them is because people often map a small part of an image and you don't know it's a link. If you can, just wrap the each image in it's respect <a href='link'>img</a>
