Title should be chosen in such a way that can reflect the content of your whole web page. So you must label all the images that appear on your web page and if possible then you should put keywords as a label for your image. So choose it very carefully. Next thing is headings or sub heading. Your first Tekster heading should be in H1 format so that it can catch attention. Another most important thing is keywords; in fact it is the only thing that affects your ranking. Because it is the keywords only that are search by visitors while searching anything on web world. It was all about Seo Tekst, now we often includes several images in our web pages to make it look interesting.
Have you ever noticed that when you move your mouse over any image on web page then you see a text that appears next to your mouse and it is called a label that you give to your images and crawlers also see that labels. Like I said, you must consistently add new Tekster to your website to keep the search engines well feed and happy. Just choose 5 to 15 phases that are related with your webpage content. These keywords will not be useful from the point of view of visitors but if we talk about crawlers then they whole crawling depend on ranking only.
