Is Alt text for images really important? Can I omit it and just pass?
Alt text is for accessibility. SEO is about priorities. The alt tag is simply a brief text description of an image. Like some older SEOs say, it’s a “nice to have”.
WordPress how to change image file name after upload?
WordPress core does not have this function. You will have to use a plugin such as Media File Renamer or Phoenix Media Rename. This means that you won’t have to delete the images in WordPress Media Library and upload them all over again from your local machine.
After changing the image Filename using the Phoenix Media Rename plugin, I notice the “/new name text.jpg” of the “File URL” automatically changes to match the new Filename. However, I also notice the “Permalink” URL still remains the same (the end text still has the old Filename included; in other words, “/old name text.jpg”). I suppose this it to not “lose” the placement of the image in the site.
Should I just leave the Permalink as it is? Yes, it is correct, you should leave it as it is.
Images usually don’t have permalinks such as a URL of a post or page. WordPress simply pulls the image according to its filename and location and then shows it within the content. Is this for a image gallery or blog post?
