Hi, @igor4wp,

I am not sure what WebP delivery method you are using, but either way I’ll send you three articles that’ll help you understand what can be happening:

• https://help.shortpixel.com/article/286-how-to-serve-webp-files-using-spio
• https://help.shortpixel.com/article/49-generate-webp-mark-up-option-doesnt-work
• https://help.shortpixel.com/article/127-delivering-webp-images-via-htaccess

Let me know if you have any questions ??

Best,

Hi guys,

Thanks for the swift response!

I’m using Using the <PICTURE> tag syntax (WP hooks) and it looks like the issue is with background pictures (which can’t be replaced by SPIO).

Are there any ways to bypass this limitation?

Cheers,
Igor

Hi, Igor!

Sure, you can try one of the following:

• replacing ShortPixel Image Optimizer with ShortPixel Adaptive Images: https://www.ads-software.com/plugins/shortpixel-adaptive-images/
• using the second WebP delivery option: Without altering the page code (via .htaccess)
• if you have an NGINX server, you can serve your WebP files in a different way: https://help.shortpixel.com/article/111-configure-nginx-to-transparently-serve-webp-files-when-supported
• using another plugin to deliver the WebP files created by ShortPixel, like Cache Enabler

Best,

Thanks @sixaxis

I was thinking about ShortPixel Adaptive Images, but not sure if I can:
– use it with Cloudflare CDN (instead of ShortPixel’s one)
– keep resized pictures longer than 30 days (to avoid running out of credits)

second WebP delivery option: I’m getting the warning “please make sure you’re serving the images from your server and not using a CDN which caches the images.”
Does this mean it won’t work with Cloudflare CDN?

NGINX server – n/a in my case

I’m using W3TC and set webp’s like that https://prnt.sc/vp3eai
Is it the optimal way as I can’t find many alternatives

Thanks,
Igor

Hi, @igor4wp!

Sure, you can use Cloudflare: https://help.shortpixel.com/article/180-can-i-use-a-different-cdn-with-shortpixel-adaptive-images

But, unfortunately, you can’t change the expiry date of the images: https://help.shortpixel.com/article/324-can-i-save-some-credits-if-i-set-the-expiry-date-to-never-or-60-days-on-my-cdn

For more questions about ShortPixel Adaptive Images, I’ll kindly ask you to open a new thread here: https://www.ads-software.com/support/plugin/shortpixel-adaptive-images/ Just to keep things organized ??

Now, regarding the second WebP delivery option (.htaccess), you are right, it does not work with CDNs: https://help.shortpixel.com/article/127-delivering-webp-images-via-htaccess

And finally, about W3TC, I am not an expert with it, so I’m not sure how or what that does ??

Best,
