This plugin creates widget (free edition) and Gutenberg block and shortcode(PRO edition) for putting online the webcam images, very useful with a weather or landscape webcam. It shows .jpg images that the webcam uploads to your server. The images are displayed responsively so that they are also suitable for smartphones and tablets. 
You can choose different CSS style and different ways to display, for i.e. slideshow, carousel, page refresh, image refresh etc.
You can publish more than one widget and Block or shortcode on the same page with different webcam.
Finally a perfect and easy way to get your webcam online!
Note: This free version uses the legacy widget system. 
On WordPress 5.8 and later, you may need to install the Classic Widgets plugin. 
The PRO edition includes Gutenberg block and shortcode support.
FREE edition: 
If your webcam uploads your images always with the same name, the free edition fits for you. It shows the latest image with a page refresh and without browser cache. 
Widget only (you may need the Classic Widgets plugin depending on your theme) 
Limited support for the free version.
PRO edition: 
Block, short-code and widget. 
-Some webcams only load one image every x minutes and the image always has the same name. The PRO version fits this! Show the latest image every time you load the browser page. 
-Some webcams load images with a different name always in the same folder. The PRO version fits that! Gets and displays the last x images found on the folder. You can choose how many images to show. 
-Some webcams upload images to a daily folder; a new folder every day. The PRO version fits this! Find the last folder loaded and then enter it, if there is another folder enter it again and then obtain and show the last x images there are. 
-Some webcams do not show the day and time of the image. The PRO version fits this! It adds a caption with the day and time of the image. 
-Some forecast sites must download a webcam image with the same name and the same URL, but your webcam changes the name of the images and the URL of the daily folder. Here is a script that searches for the last image of your webcam and always saves it with the same name and the same URL. To do this you need a cron job. 
-Two beautiful style settings and extra Bootstrap style also. 
-A slideshow that can show the x number of the latest images with a carousel mode. You can choose how many images show. 
-Also, you can set to show the latest one image with an auto image refresh every x seconds (no webpage refresh, only image refresh). 
The PRO version is full of adjustments and ways to show images. It is fully responsive and displays well on smartphones and tablets. 
Support by tickets system for 30 days.

This plugin lets you show the data from Meteohub all-sensors.txt file easily in the content of your website using shorttags.
For example: 
 Temperature: [meteohub sensor=’actual_th1_temp_c’]°C 
 Max windspeed: [meteohub sensor=’alltime_wind0_maxspeeddir_nl’] [meteohub sensor=’alltime_wind0_gustspeedmax_bft’] bft ([meteohub sensor=’alltime_wind0_gustspeedmax_kmh’]) on [meteohub sensor=’alltime_wind0_gustspeedmax_time’]
 will result in:
 Temperature: 9°C 
 Max windspeed: NNW 12.4 bft (130.3 km/h) on 28-10-2013 at 12:31
The plugin automatically rewrites the date and time according to your WordPress time and date settings, and trend values get rewritten to arrow images.
I am in no way, shape or form affiliated with Meteohub and do not in any way profit from commissions or referrals to them.
