1) Keyword Phrase in the File Name
Having the keyword phrase in the file name would benefit you a lot as far as Image optimization is considered. Sensible placing of keyword phrases in the image file name would give you additional benefits of your image being found in the search engine results for image searches. The file name should be short, but needs to describe what the image is about with clever keyword placement without spamming.

2) Keywords in the ALT tag
ALT Tags are the content which describes about the image textually and is mainly meant for users as well as search engine spiders. Including the keywords in the ALT Tags can improve traffic from image searches.

The size of the image plays a major role and an image with bigger size would make a delayed browsing experience. As we know that Google gives some importance to page download speed for better search engine results, it is always a good idea to keep the image size under a specific limit.
5) Making the Images folder Crawlable by the Search Engines
In some cases, the image folders of a website are blocked for the search engine spiders through robots.txt files. This should be removed and the search engine spiders should be granted permission to crawl them for better search engine results.
