I don´t know all the image filter that uses beacon, but for sure resize_rendered_image_dimensions is one of these image filters, but other filters, css related, uses it too (the prioritize_critical_css). Beacons returns back to server some info, like if the image is in the viewport, what are the rendered dimensions, what is the critical css to load and what css to defer....So disabling beacons most of the image filters don´t work well nor the prioritize_css_critical. By default, pagespeed works with a "core" rewrite level. This level enables a bunch of filters. An alternative is to use the `pagespeed RewriteLevel OptimizeForBandwidth` this rewrite level do some optimization work and can´t rewrite the html code at all. Other is use of `pagespeed RewriteLevel PassThrough` this one only enables the filter you explicitly enable.
