Hi,
Here are some important points to consider
- When you upload an image to a webpage, make sure that the webpage is public and accessible by visitors
- Use alt tag for image to describe your image. This will help Search Engine to understand what the image shows and where it is more relevant.
- Once you have uploaded the images, keep calm, and wait for some time. Let the search engines crawl your site and they will do the rest. There is no timeframe for this, so be patient.
