Images not showing on mobile portrait

Hi everyone,

I have created a webpage with different tabs. On the second one, not all images are showing on mobile portrait in the dropdowns at the lower part of the page.
However, one image is showing and they all have the same Class …

I have read other topics on this subject : tried to set the width to 100%, tried to set width and height to 100%, tried to change the Slide class to display:block as well but no luck so far …

Thanks in advance for the help !
