I am considering to move my images from folder
site/userimages to subfolder
The changes will be done in PHP files regarding the path change so that images do continue to show up on the main board of the site, however is it well reqd to show to search engines that the path folder is changed.
I mean as the images will keep on contuing to show on the front end of the page. Is it also important to let search engines know that the folder has moved to a subfolder in the site through .htaccess redirect.
Note: the images are well indexed by search engines.
