Missing image alt-tags in galleries and page-attachments
After days of fruitless search I thought I might possibly get help here.
I just set up my first self-hosted website. the poetic dimension of photography is a photographic portfolio site. In the process I read a lot about the importance to improve seo criteria and how especially image based sites need to have image alt-attributes/-tags. So I diligently filled meaningful alt-texts for each photograph in the media library (most of them after uploading I think).
The problem is that all the HTML-pages showing the fullsized images do not contain these alt-texts. If the fullsize images are accessed by clicking a smaller version in the shortcode-gallery of a blog post then the rendered alt-attribute is merely a duplication of the title-attribute. If accessed via the gallery of images attached to a page, both, title and alt tags seem to be absent (if my reading of Firebug is correct). Accordingly xml image-generators (and search engines I suppose) also find only these identical title and alt tags when crawling the galleries and the wp-content/uploads section.
I use the photonexus premium theme. But as I have read about certain title-alt-tag-issues as well as missing alt-tags in galleries concerning earlier WP versions (the threads that I could find were unresolved) I think it is probably not a theme issue. Of course I may be wrong here.
Just to outline the site’s structure: Images are attached to the pages that are listed by a photo menu in the sidebar (and not to posts). In addition the images are included in blog-posts via the gallery shortcode (and not inserted) – in a smaller version.
Interestingly enough alt-texts do appear in the sitemap (and the HTML-pages I guess) for the thumbnails 150×150 . They are generated by Timthumb as far as I understand.
Is there a way to have the image alt-tags as specified in the media library rendered in HTML-pages for the fullsized images, and have them updated if edited in the media library?
I must add, I am not capable of coding, but I could do some minor alterations if someone told me exactly what to do.
I will greatly appreciate any help or clarification!
