Are there any generally recommended best practices for image size requirements? Mostly looking at desktop vs. tablet. Is it generally accepted for a a RWD site that a separate set of smaller image should be used for tablet vs. desktop?
Right now, certain landing pages have images as high as 1mb, and a total download of around 4.7mb. Should I be concerned? Once again, only concerned about desktop and tablet. Assumption is that on average, a tablet user will have a slower connection considering slower processing speed, possibility of being on a 3g or lte connection, or connected to wifi.
Here's a link to a sample page for insights. Thanks!
