As suggested by our SEO guys, they wanted to show title tag on product detail page's thumb images. I am able to manage other image's title tags on the same page but not able to set title tag here. Here is screenshot for more idea. http://nimb.ws/hX74Fr
Following files I have modified and added title but no luck.
getGalleryImagesJson() function, added title tag
getOptions($currentProduct, $allowedProducts) function, added title tag.
I assume above files and willing to override if these are the files only. Any help will be highly appreciated.
Thanks in advance.
