Hello sir,
As far as I understood from your description, you need to add alt tags to every image. This is an opportunity in freelancer for starters like me and I would appreciate it if you award me the project.
The task is pretty simple. You will have to provide me with the descriptions you want to add in alt tag or I can process a JQuery function so the alt tags are generated by itself according to the source of the image. This is advised to be done only if you like the alt tags consist of the image name.
Image name can be edited removing extensions.
If all images are coming from the same folder, even their paths can be removed accordingly, leaving out only the name of the picture, which can be a nice alt tag
I would like to add that some images that you have prepared are assigned via CSS background. This means there is more mechanical work to it then described above. Images should be added as img attributes and the appearance should be kept the same way. Then the script I described above can be applied in no time
Hope you liked my script explanation. Please, do not hesitate to contact me if you have any question.
