Images you upload to your website can now keep their original file name, instead of being automatically renamed.
This provides several benefits, primarily including better performance in search engine results:
Since search engines can’t see and understand a photograph, they rely mainly its file name to describe what’s in the photo. When the file name provides no useful info (like just being named “image”), search engines don’t know what’s in it. But if the file were named something like “smith-wedding-2014.jpg”, they’ll associate the keywords “smith”, “wedding”, and “2014” with the image, and start displaying the image in related search results.
Overall, this is a somewhat minor change, and something your visitors will likely never notice, but will help your work get more attention as part of our ongoing effort to give our clients the most effective websites possible.
