Why is the file size for email images restricted?

The maximum files size of images is restricted to 150Kb.


This is to ensure that people receiving your emails (for example on mobile phones) do not have to wait a long time for the image to download. 


It also prevents them incurring possible data charges when downloading large images.


Recommended best practice for email images suggests a maximum file size of 100Kb.
