That's right, but i dont want to use titles, cause i think it would worsen the look, feeling and design of my gallery - with this setting, my gallery is almost invisible to search engines. Apart from that, many times the title of an image is not suitable to be used as alt tag.

Do not you want to show titles under thumbnails or show them in lightbox?

I don't want use image-titles, neither in the thumbnails nor in lightbox. I need to set an alt tag for my images without using a title (or describtion). I don't think it's possible with the current release, so i just want to give you an "urgent" feedback for the next release, cause i really hope you will implement this feature soon.
As i have already mentioned, all my gallerys are invisible to search engines (you can test this with a text browser like 'lynx') and that's really bad.

If we add ability to use "Alt" column from a CSV file as "alt" attribute for <IMG> tag, is it suitable for your needs or you have another idea?

Yes, that would be really great

Maybe it's possible to add a fourth column in the describtion file (csv), where it's possible to set the alt tag.

Download and upgrade "ARI Pretty Photo" module. New version uses values of "Alt" columns from a CSV as "alt" attribute of <IMG> tag if it is defined in CSV file.
