Small clarifications for a newbie

Hello, I am fairly new to web accessibility. I did the Introduction to Web Accessibility course (W3C/edX). I do not have a great background in development (HTML/CSS only not much of anything else). I'm using Typo3 CMS. I need to work on the accessibility of my organization website, but sometimes I have questions about whether a problem really needs to be fixed.


1- We have "icon blocks". These blocks are composed of a link on two elements: an image and a title. <a><img></img><h3></h3></a> . The image sometimes has 2-3 words of text, but the same words are also used in the text. Is this okay? We should avoid text in images, but since there is text next to it in the link, is it okay? Also, does the image need an alternative text?

2- When I have an image of a book cover next to its title. Both elements are clickable. The image is only for aesthetic purposes, but since it is also a link, should we put an alternative text even if it is the same as the book title?

3- In a procedure, we explain that the user needs to click on a button. We have an image of the button in the text to facilitate recognition. I assume that we put an empty alternative text because it is redundant with the text (please validate). If we put an image of the entire screen with the button highlighted, potentially with an arrow, should this image have an alternative text or should it be empty?

4- If I have a table, is it ok to only use header (H2,H3...) or do I need to use caption?

Thanks a lot! :)
