My blog is image based, and I have been adding keywords in the title box when uploading images, to create alt tags to help Google searches. These keywords also appear as the alt tags (and title) in the HTML editor, i.e. as title = "keywords here" & alt = "keywords here"
However, sometimes I remember a keyword I should have included in the title after I've posted the image. If I were to add an extra word in the HTML editor (after alt=), (as opposed to laboriously reuploading the image and retitling it), would doing this have any adverse effects in terms of the code not matching up with the media library code? I'm just worried that altering the code might cause a break in the link to the media library image.
