Serve Images in Next-Gen Formats

Hey Tim, 

Yea, but we'd need to support legacy formats as well.  Can you let me know how you want to implement it in a page and benefits? (the why)?

In general I think I'd like to build/find a separate image thumbnailer/processor.   Let me know some more details on what you want to do.

Thanks!

Hi Dave.

I guess I would see it working that every standard image created from the upload (original + thumbs + crops) would have 2 versions - the original format plus the WebP.  Then allow the browser to choose which image format to use.

So, the code generator would output the various different images as usual, ut with the alternates as well.

I would use something like the following in the page code:

<?php foreach ($record['thumbnail'] as $index => $upload): ?>

<picture>
<source srcset="<?php echo htmlencode($upload['urlPath_webp']) ?>" type="image/webp">
<source srcset="<?php echo htmlencode($upload['urlPath_jpg']) ?>" type="image/jpeg">
<img src="<?php echo htmlencode($upload['urlPath_jpg']) ?>" alt="Alt Text!">
</picture>

<?php endforeach ?>

Here's a good summary of benefits and use: https://css-tricks.com/using-webp-images/ 

Hey Tim, 

There's a neat library here that dynamically redirects .png/jpg image urls for supporting browsers and generates .webp images:
https://github.com/rosell-dk/webp-convert/blob/master/docs/webp-on-demand/webp-on-demand.md

We couldn't potentially build something as well.  

That certainly looks easier to implement on my side :)

Hello Dave & Tim,

The library link doesn't work anymore. Did you had a copy of the library? or how did you finally get this thing going Tim?

Thank you!

Hey Jesus.

I never went further with this - although it's something that keeps raising it's head wanting attention.

Hey Jesus, 

That library is now part of WebP Convert, which you can find here:

Cheers,

Hi Greg, thank you.

I'm still lots with the library as I don't need to convert files on the fly or similar. I've already my jpg and webp images properly located in the proper folder but I'm trying to figure it out how to call the proper image using the <picture> tag

<?php foreach ($record['imagen'] as $index => $upload): ?>
	<picture>
		<source type=“image/webp” srcset=“image.webp”>
		<source type=“image/jpeg” srcset=“<?php echo htmlencode($upload['urlPath']) ?>”>
		<img src="<?php echo htmlencode($upload['urlPath']) ?>"
	</picture>
<?php endforeach ?>

I uploaded the webp images manually to the same folder where I've my current CMS images.

or should I create a new upload field and then upload the webp image from the CMS and then try to use an IF statement to load the proper image (jpg or webp)?

Thanks for pointing me to the right direction

Jesus
