Image Compression

Yes, that is a lot clearer. I guess sticking with the default breakpoints is best then? The breakpoints i thought i had to add were to cover mobile to desktop devices as follows:

desktop – 1405
laptop – 1100-1405
Tablet landscape – 981 – 1100
Tablet portrait – 768 – 980
Smartphone landscape – 480 – 768
Smartphone portrait – 0 – 479

So from that i used the following as my breakpoints:

1405, 1100, 981, 768, 480

Would these not be necessary, and i would be better sticking with the default breakpoints?

I use Godaddy managed wordpress which has built in caching server side. This is not cdn, but i had initially checked cdn support as the description said “or other external caching solution” so i thought that applied to me. But having this option unchecked seems to work well, although i will have to test this more thoroughly tomorrow. But so far disabling the options i had enabled results in much more images being cached.

Well, the default breakpoints are just “good defaults”. To be honest, I guess one should only change them if they have a specific need that they know about.

Now, I am not sure how the internal caching of Godaddy works, but it seems that your description and your initial perception were correct in theory. Let me know how your tests go!

Could you explain what you mean by “a specific need”? My intention with setting those breakpoints was to try and deliver an image size that is most appropriate/optimized for the device size.

In the setting there is an option for HiDPI support. Does this mean retina support, so images with @2x will be served to retina devices?

By “specific” needs we mean cases where one knows the exact devices their website targets. Or just if one wants to tweak the resized images in a different way than the default in order to achieve the same thing.

The HiDPI support will serve double sized images to such devices. Of course this means bigger file sizes, this is why it it optional.

That’s great, thanks very much for your help!

You are very welcome!
