Hi Naavya Jain
The screenshot is not attached. kindly attach it for more info but I can give a suggestion based on your prompt worth checking
Your widgets aren't inside a data container scoped to Course.Showing one course → add a Data View, set data source to Context → pick your Course page parameter, then put widgets inside it. Attributes will become selectable.Showing a list → use Data Grid 2 / Gallery with data source = Database over Course.
Can't delete the default image It's a Dynamic Image widget. Just select the widget itself and press Del. If it won't go, it's inside a snippet/layout open that to remove it. To only clear the picture: widget properties → Default image → (none).
I hope this helps
