For the Pi-hole plugin, I created an image zip file as described on the Wiki. They are 48 x 48 px. However on the Domoticz pages they are sized to 40 x 40 px!
This is the 'old' style of sizing images. It should be 'style="height: 40px, width: auto;"' or some thing. But with the current attributes my images are ugly:

while in the Custom Icons I see:

- Knipsel2.PNG (3.05 KiB) Viewed 429 times
Much more better! Should I resize to 40px?
