Hi CEd,

I'd like to display the picture of a webcam using the "Single Image" widget.
Is there a way to force the browser to load the image from the server rather than from the local cache anytime the page is loaded?
Any recommendation ?

Many thanks,
Volker

Hi
I don't think that your request is related to Page Builder CK, because it does not manage the cache of your browser / server

Hi CEd,

thank you for your fast reply !
I mean I'm using Page Builder to create the home page for my site. And in there I'd like to display the image of a webcam, which is refreshed every 5 minutes (by overwriting the image with the same name on the server) . I'm using your default "Single IMage" widget to display this picture.
Now, when I'm opening the webpage, usually not the most current image is displayed, but an older one, which the browser loads from the local cache. If I want to see the most current picture, I have to hit F5 to refresh the page. My question was, whether you see a way, to force loading this picture from the server any time (i.e. by some additional java script; there are a few samples on the internet).

Thanks,
Volker

the answer : no, I don't see a way to do that :)
the fact is that your request is totally not related to Page Builder CK, even if you are using the image addon to load it. It creates an html code to render your image in the browser. Do you understand what I mean ?
there is no feature for that in Page Builder CK

Now, may be that I have an idea : in the url you shall add a variable , this way your browser see it as a new image each time
You can do that using the "code" addon in Page Builder CK, and put your image code there
Example :
Code:
<!ck-php $imgtime = substr((int)microtime(true), 4); php-!ck> <img src="/images/pagebuilderck/ble_r055.jpg?ver=<!ck-php echo $imgtime; php-!ck>" data-src="/images/pagebuilderck/ble_r055.jpg?ver=<!ck-php echo $imgtime; php-!ck>">
You will need to adapt the image path

Hi CEd,

I need to apologize; I'm not a real web expert. So I may ask stupid questions sometimes :)
I'll give your suggestion a try, it sounds promising !
Thank you,
