We should remove the inline base64 encoded images, that are being used on some websites, in page processing before being sent to the GPT. It's useless and wastes a lot of tokens.

@JJetmar Can we please have more info on how to priorize this?

@PavlinaVencovska Well this makes the scraper unusable when website contain images with such a sources. There might be a simple workaround (not tested) by setting selector img[src^="data:"] for elements to re removed though.
