Unable to see image in webview version

I’m using desktop version for 3 years but when recently it is updated to webview version then images already added were disappeared.
but previously they were shown. but when i install webview then images disappeared

You need to furnish more information. Disappeared from where? What does your screen shot show if not your images? And what does your screen shot depict? How were your images included? Basically, you have provided no place for anyone to start with offering help.

I’m using this code to include images as shown in screenshot
but when i installed WebView version then images disappeared from inventory items.
I’m using custom field of image in inventory item section to add images.

Please answer the question: “Disappeared from where?” Where are you entering this code?

like i said I’m entering this code in inventory item section to display images of inventory items.
i add custom field of image in inventory item and add this code in it.
from where manager automatically pickup images from folder.
like i share first screenshot

No, you did not say that.

While some users (mostly Windows users) report success storing images locally, the image-type custom field feature is designed for storage at a web-accessible URL. This is plainly stated in the Guide: https://www.manager.io/guides/16188.

so that means i have to post all the images at some website and then manager will get them ?

Yes, that is how the program was designed to work.

Yes they did in post 2 - " images disappeared from inventory items"
What’s the difference between “inventory items” and “inventory item section” ???
