If I host an image on a web server I'm running internal on my network, it should display on the local dashboard, but what about on the cloud dashboard? Does an internal hosted image for the dashboard get pushed out through the hub for the cloud dashboard to use?
Does the cloud dashboard put the dashboard together internally and then send it out to the cloud? I'm trying to figure out how it works. I'd like to host some pictures on my dashboard and have those same pictures be on the cloud dashboard. I'm also wanted to only have the web server be internal only. No external access.
If you are running a web server, is it a Linux based server? If so, then this is what I do to make sure my images are available for the R-Pod Owner's Forum:
Place a copy of the image to share in /var/www/html/(image directory if desired)/image.jpg/png, etc.
Use a service like DNSExit (free) (or DynDNS (pay) or other DNS service) to enable access to the web server from outside your network. I would configure the web server to use a non-standard port to cut the traffic such as 8080 or 8008 or something like that and configure your firewall and SELinux to accept the non-standard port.
Scale the image to something reasonable. 800x600 works well. 640x480 would look good on a phone also. The scaled image will take up less space and transmit faster. You can use a program like the GIMP (Gnu Image Manipulation Program) for this purpose or any other image editor that will let you do the scaling.
If you are using Windows, you are on your own but the principles should be the same.
Here's an image just to show you what I am talking about:
If you don't publicize the links, it won't be available for just anyone. You could go farther than I did an limit access to the images to you alone by requiring some sort of password or token to access the images. A web search will lead you to information on how to implement this.
@BorrisTheCat were you able to use a pic stored in Google photos as you suggested? If so did you have to do anything special as far as sharing goes to make it display as a background graphic? jpg or png, does it matter?
