Very useful tutorial on adding a Staff Profiles section to your Silverstripe site here: https://docs.silverstripe.org/en/3.3/tutorials/extending_a_basic_site/
Used it before and it worked fine. Have just added it to another site -- the CMS backend part works fine -- images have uploaded to /assets/uploads but are not showing on the page??
As per the tutorial, code to upload images is
$Photo.ScaleWidth(150)
Have I missed something??
