I am a beginner and have read numerous threads for adding alt tags to images in CC. Some say you have to add them when you upload the images but I tried that and it doesnt work. When uploading images there is only a "browse" button and nothing else on the page. I need to update all of the image alt tags for all the existing images already loaded into CC for SEO purposes so if there is a way to do it without having to upload each one again, even better. Where can I add/edit this info? THanks in advance for your help
