Search Results not showing PNG images

We have found a bug where search results aren't showing images that have been added with PNGs

You can see an example here:

Is this a known bug please? The properties which aren't showing the images on the results page are showing fine on their actual property page

Hi Rusty,
Actually, the issue is not that the images cannot be loaded, but that the resized images are not being generated.

Please click on the Support Ticket menu at the top, then create a new ticket in the OS Property category. Kindly provide your site information and administrator account so I can check the issue for you.

If you have any questions, please let me know.
Thanks
Dam
