Why listing images don't show on front-end of website?
If you uploaded the images on the backend Add/Edit Listing menu and they are shown just fine on this menu but they're not shown on the frontend, then please check the following:
1- Make sure the gallery activities are enabled.
Navigate to WPL->Activity Manager and search for the "gallery" term and then make sure the activities are enabled.
2- Make sure the images are enabled.
WPL has a feature for disabling listing images. The images are enabled by default but sometimes our clients disable them by mistake. Please edit your desired listing and navigate to the Gallery section and make sure a tick icon is showing in the right section of the image box. If it's cross icon, then click it to change it to tick icon.
Note: Media Confirm feature is disabled by default so you don't see tick icon unless you enable the Media Confirm first from the WPL->Settings menu.
3- Make sure that gallery activity is accessible by all users.
WPL activities have a feature for managing display access. You should make sure that gallery activity accesses and Page Associations are set correctly.
