You problem is here:

@media screen and (max-width: 480px) {
    .inicioEmpresaInfo .empresaImg {
        display: none;
    }
}

At this size, empresaImg (the container of the image) become hidden

Try giving the image padding and or margin in the CSS:

@media screen and (max-width: 1366px)
.empresaImg div img {
    width: 95%;
    padding: 25px 25px 25px 25px;
}

This may force the image to fit in the screen. Otherwise you will need to look into conditionally rendering different sizes of the image depending on screen size. Check here for answers on that.

css:
you can see with f12 or element inspector of chrome or mozilla, here is a screenshot showing the elements applied to such image:

css code applied to the image:

@media screen and (max-width: 1366px)
.empresaImg div img {
    width: 95%;
}
.empresaImg div img {
    width: 100%;
    border-radius: 5%;
}

also saw this, when you change the resolution in >element inspector > mobile icon click > resize from 488 x 625 screen (the image will appear) but when i change from 488 x 625 to 480 x 625 the image will disappear!

 @media screen and  (max-width: 768px) {
    
    .empresaImg div img {
        width: 100px;
        height: 100px;

.empresaImg div img {
    width: 100%!important;
    height: auto!important;
}

but did not worked still disappearing in < = 480px resolutions

here is the responsive css in charge of making it responsive, i do not know where is the error also tried to forcing the image to be 100×100 px and in resolutions below width of 480 it breaks:
