full width image slider

Hi, there,

How do you know that every third image is ignored? I tested with webpagetest.org with mobile Chrome emulator on and It seems that all big images of the slides are resized. The test is here https://www.webpagetest.org/result/150521_YF_10MP/1/details/.

And this is what it says for the big images:

https://www.dreilaend...4/07/aussen-0680.jpg image/jpeg 150.7KB
https://www.dreilaend.../2014/06/fassade.jpg image/jpeg	150.2KB
https://www.dreilaend...4/07/aussen-0676.jpg image/jpeg 151.6KB

Is this not correct? Should I test something else?

Hi
I tested on google chrome emulator.
The size for every third image was the original size. No resize.
Ok, maybe i did something wrong.
But with the other, smaller slider, google returns that all images are beeing resized.
I’ll check your link and verify your result.
I will let you know.
Thanks for your care.

Ok, i have seen your results. Since they all have the same weight in KB i conclude that the resize happens for all images.
This is the result i get from google (sorry it is not english):

Die Gr??e von https://www.dreilaendereck-basel.ch/.../terasse.jpg wird in HTML oder CSS von 1920 x 1200 zu 1016 x 640 ge?ndert. Durch die Bereitstellung eines skalierten Bildes k?nnten 138.0 KB (71%) eingespart werden.
Die Gr??e von https://www.dreilaendereck-basel.ch/.../aussen-0676.jpg wird in HTML oder CSS von 1200 x 800 zu 955 x 640 ge?ndert. Durch die Bereitstellung eines skalierten Bildes k?nnten 55.0 KB (37%) eingespart werden.

As you can see one image keeps the original dimensions.
Probably a mistake.

Anyway thanks a lot for your care.

I am not sure if the Google emulator actually behaves like a mobile device! It must report its screen size as a mobile device. If it reports a screen size of the desktop computer then there will be no resize by the plugin.

On the other hand the webpagetest.org can test a website like a real mobile device. It has settings for this. Check it out!

So, this is probably the same reason that Google does not report smaller image sizes, too! I do understand a little German ??

Hi Nevma
Thanks for the message.
I will test the site with webpagetest.
Have a pleasant day.

Hi Nevma
I tested the site on webpagetest, gtmetrix and google.
The results are good.
Thank you very much for your help and for this great plugin.
All the best for you and your work.

Thank you so much for your feedback!

I know that webpagetest.org has good mobile environment emulation. And I use it myself all the time. Does gtmetrix have such a capability too?

Hi Nevma
Yes, gtmetrix provides a mobile emulation and a very good interface.
This is the specification:

Test Server Region: Vancouver, Canada
Using: Chrome (Android, Galaxy Nexus) 26.0.1410.58, Page Speed 1.12.16, YSlow

As with webpagetest mobile emulation is limited. For GTmetrix the testpoint is Vancouver.

I will try to use both then, thanks!
