Does the content editor automatically resize images?
The content editor does not automatically resize images when it uploads them. You are able to scale an image in the content editor when you insert it however it is not recommended to do this for more than a 10% size difference. Visitors will need to wait for a large image to download to their browser even if it only displays on the page as a small image. For best results resize the image in an image editing program before uploading the image to your site.
