This is not a PWS-dashboard problem, it is a http://collapit.ddns.net:8081/ problem.
Using an iPad: I tested with your site and with Leuven Home Weather Station (wf version) (also uses WU + webcam)
Your site does not display the webcam image most of the times as the image from http://collapit.ddns.net:8081/ never fully arrives, the browser is still trying to load data, even if the data is “almost” there.
I opened http://collapit.ddns.net:8081/ on the iPad it never shows the received data.
On a mac it shows the image but still tries to fetch more data.

I think you should change is in such a way that the camera should not be accessed for the image.
The image should be uploaded every so many minutes and then accessed from the website as a normal image.
