Total combined Image content size is too big (over 1MB)
URLs for which the total byte size of all image content is greater than 1MB.
Why is this important?
One of the easiest ways you can improve page load speed is by optimizing images and properly sizing them to the size that is rendered. If you have a page with large images, lots of images, or poorly compressed images this will have a negative effect on load time and increase bandwidth.
Studies have shown that image weight is a key driver of overall page weight, which ultimately leads to slow load times.
What does the Hint check?
This Hint will trigger for any internal URL where the total image size is over 1000KB:
How do you resolve this issue?
There is no hard and fast rule as to what determines a page size as being 'too big', so from that perspective the threshold of 1MB for image content is relatively arbitrary. Graphic heavy sites/pages necessarily have a higher image weight, so there is no 'one size fits all' recommendation, but it is still an issue that deserves consideration.
Use this Hint to identify your worst offending pages, then you can check to see if they have far too many images, unoptimized images, or images that have not been properly scaled (or multiple issues have compounded on certain pages).
