Thanks. So I actuallyhave to consider file name of image, title text of image and alt text.
The website we are using is delivered from a company - so quite some of the coding etc isnt accessible by me. I am just adding the picture and text. So my way to do this i guess have to be to 'mark' the image with the necessary info before uploading it to the site.
I think i use title text. When clicking image on our website that takes you to the product page where there is a description of the product or image. At least when i use seo-browser part of this product info seems to be applied to the picture but not in full (eg when I profile a product image on home page) there is a part of this product info shown when opening source of homepage.
EDIT: I might have to talk to my webshop provider. My basic knowledge is a bit sparse but it isnt possible to add HTML to an image file eg .jpg and still keep it in an image file format ? What i do basically in our webshop is to upload the image in the 'right' folder and then add the image text. This is done for maybe 70-100 products 2-3 times a year. Adding it in the code isnt available to me and doesnt seem like an option with this volume ?
Anyone have any ideas ?
