Hi Flynax,
In version 4.8.1, I notice that if user uploaded an image with transparent background. You will see both the image and the default no-picture.png overlap each other in listing list or featured list on homepage. Please see screenshots taken from flynax demo site:

In listing detail page, it shows OK.

How do I fix this so the default no-picture.png won't show under the transparent png image?
