Good thread points from , , and others: alt text, file names, compression and sitemaps are the basics. Below is a short, modern checklist that fills gaps in the replies and gives practical steps that work today (performance + discoverability).

Start with semantics and accessibility — descriptive alt text and human-readable filenames. Use concise, meaningful alt that describes the image’s purpose; mark purely decorative images with alt="". Filenames should be lowercase, hyphen-separated and descriptive (not IMG_1234). Avoid keyword-stuffing in alt or filenames — write for people first and search engines second. (w3.org)

Serve images that match the display size and format. Export several sizes and use <picture> / srcset + sizes so browsers pick the right file for the viewport and DPR. Prefer modern formats (WebP/AVIF) with JPEG/PNG fallbacks where needed. Lazy-load off‑screen images (loading="lazy"), but do not lazy-load the LCP/hero image — instead preload or use fetchpriority="high". These steps reduce byte weight and improve Core Web Vitals. (web.dev)

Prevent layout shift and speed up rendering. Always provide width and height (or an aspect-ratio placeholder) so the browser reserves space and avoids CLS. Compress images with a visual-quality target (experiment at 70–85% for photos), and use CDNs or an image pipeline that auto-generates variants. Validate gains with Lighthouse / PageSpeed Insights and iterate. (web.dev)

Discovery and metadata: include images in sitemaps or add ImageObject/IPTC metadata for licensing and richer presentation. If third‑party hosts or CDNs are used, ensure crawlability and Search Console verification for those domains — otherwise indexing and attribution can be affected. (developers.google.com)

Reference snippet (copy/adapt into templates):

<picture>
  <source type="image/avif" srcset="photo-800.avif 800w, photo-1600.avif 1600w">
  <source type="image/webp" srcset="photo-800.webp 800w, photo-1600.webp 1600w">
  <img src="photo-800.jpg" alt="Red ceramic mug on wooden table" width="800" height="533"
       sizes="(max-width:600px) 100vw, 800px" loading="lazy">
</picture>

Troubleshooting quick checks: failing LCP? check that the hero image isn’t lazy-loaded and consider <link rel="preload"> or fetchpriority="high". High CLS? ensure explicit image dimensions or aspect-ratio placeholders. Images not indexed? confirm they’re embedded with <img> (not CSS), crawlable, and listed in the sitemap.

Most important is File name
Before put Online you should change your image name as your targeted keyword and do some submission on High PR site like imgur
That's what i used to do. Thanks

Yes If we optimize the images, images do rank in Search engine.

While uploading images, make sure to give proper image name. Since Search engine can't understand or read images, we need to add ALT Tag, which is HTML syntax to let the Search Engine knows about images.

Compress the image.. Use alt tags and use your focus keyword..

Member Avatar for Marek_5

you just need to do, resize if the image size is larger than required. Consider always Image Size, alt tag of the image.
Update ALT Tags for all of the images with a specific keyword you are using. It will help you to get good search ranking position on the Search Engine Results Pages (SERP).
