Hi, the chrome page crash can mean it used all of the memory.
As you found, this can be caused by the images.
Images are a bit tricky, if you put an image with a modified width/height attributes to HTML, the chrome still embeds the full-size images to the pdf and this is consuming a lot of memory. If this is your case, I recommend resizing your physical images upfront to the desired size. You can do this manually or programmatically.
See an example here:
