Lazy load img tag

Hi all!

My request is to be able to output lazy load within an image or thumb output tag:

eg. txp:thumbnail id=“298” loading=“lazy”

Would be super handy!

Hi Hilary! Would it? It is, since 4.8.something.

I’m often ahead of myself. I thought it worked only in <txp:images />, before some testing.

Re: Lazy load img tag

It is handy but only (currently) works in the individual image tags. Using it in <txp:images> would require passing that attribute forward to all the tags in the form/container (i.e. setting a globa flagl) so they all have the attribute set by default. At the individual tag level, it then needs to be possible to override the global flag as set in the wrapper.

Code-wise that’s all pretty grungy so we’ve left it at the tag level for now. And if you’re using a form or container, you usually only have one or two <txp:image> or <txp:thumbnail> tags inside it anyway, so it’s not much extra work to add the loading attribute there.

Hope it’s helpful as it is.

My memory is even worse than I thought, thanks for the reminder.

And if you’re using a form or container, you usually only have one or two <txp:image> or <txp:thumbnail> tags inside it anyway, so it’s not much extra work to add the loading attribute there.

And if you have many manually added images inside Body (and are lazy, unlike the images), a quick-n-dirty trick should do:

<txp:body trim="<img" replace='<img loading="lazy"' />
