Image Search Optimisation (ISO) is the process of organising content of a webpage to increase relevance to a specific keyword on image search engines. Like search engine optimization, the aim of ISO is to achieve a higher organic search listing
for images, usually photos, and thus increase the volume of traffic from
search engines. Image search optimization strategies can be viewed as a
subset of search engine optimisation strategies that focuses on gaining high
ranks on image search engine results. Unlike normal SEO, there is not much
to do for ISO. Making small data file size, interesting images accessible to
search engines and providing some description about images is almost all
that can be done for ISO.
HOW TO OPTIMISE IMAGES FOR THE WEB
Use a computer graphics softare like Photoshop to "Save for the web" at
the "medium" setting.
If you don't have computer graphics program you can optimise images with
either tinyjpg.com or
of many free image optimisation plugins for WordPress which bulk optimises images. Some CDNs can convert jpg images to Google's .webp formats which has an even higher image compression (smaller file size) and serve your images from data centres in 6 of 7 continents. Some WordPress image optimiser plugins like EWWW can also automatically convert your image files to .webp and other new image compression formats.
Most digital camera's create huge photo file sizes that are much too big for the web. (OK for billboards).
Ben recommends you reduce the width of images, except maybe header images, to no bigger than 800 pixels.
Digital cameras produce bad photo file names. Eg IMG12345678.JPG
Rename image file names to what the page is about.
Image alt tags should be in line with the SEO target phrase of the page/s the image will be on.
Examples of Image Search Optimisation:

How to market your images for image search optimization
There are a number of ways you can get lots of views of your images via SEO of web pages they are on or social MEDIA marketing. Since Google is a popular search engine, it's good to work with what Google wants and all the different free Google offerings. Eg:
- Google Maps
Google My Business
- Google Drive / Your Google Photos.
- Google+ (it's still alive for Google Suites users and is renamed to "Current")
Other other online photo storage/libraries such as the popular Flickr are worthwhile too.
Copywriting for SEO with your photos and tagging photos is another ISO tip.
