No bug no conversion to webp format

Hi Hervé,
webp depends on server support.
here is some more info and a way to test if it is supported on the server: onlinecommunityhub.nl/documentation/ochr...n#webp-image-support

-> Subsidiary question
I found the interesting function of the plugin "action media resize" of joomla 4.
I set 800px as the max value of the height/width.
Note the size of the resized image is larger (jpg & png)! Maybe a bug?
If I understand correctly using your plugin, the transformation after webp arrives at the end and stores the image in a cache directory.
All this seems to you coherent and correct?

Goodmorning Hervé,
ochResponsiveImages is a system plugin that takes the content of the page as input. it searches for <img> elements. When the image in the lement meets the requirements for replacement (size), it will create 'cached' images (both original format e.g. jpg and webp) of the image: for each breakpoint configured it will create a 'cached' image. The 'cached' images are stored in 9default config) /images/ochri directory.
They are actually not cached (cache expires and rerfeshes after set time), but normal images that do not expire.
When you delete the contents of the images/ochri directory then the images will automatically be recreated.

So this is how it works.
I do not know the plugin action media resize (and do not need to know of it: as said > ochResponsiveImages works with the resulting page.
Only thing that could go 'wrong' is that ochResponsiveImages is set to run before a plugin that alters the size of the image.

btw. The power of ochResponsiveImages is that you do not need to resize the images. If you have an image of 10.000px wide and display that as 800px (what the average user does: upload the big file and resize by setting width/height), ochResponsive images will create and use in a scrset the correct sized images for you. Automatically without resizing the source image. And this is important because when you later on decide to not display it at 800px but at 1200px, you would have lost the original image and end up with an 800px image that will be upscaled (= less quality) to 1200px.

Would it be possible to take this into account with your plugin. As a maximum display size 800px * 800 px, which would allow me to automatically resize with the plugin "action media" 1200 px * 1200 px ... for example!?
 

Hi, that is not possible: ochResponsiveImages is not intended as a scaling tool. What you put in, you will get out: visually the same.
As for the storage: yes, every image and every image version takes up diskspace. That cannot be changed with ochResponsiveimages. If you want to limit the upload size of an image you should do that with another field / tool. ochResponsiveImages is not an image / media upload tool. It 'just' makes what is (an image) responsive and performant following google best-practises.
