AMP – Defer/Properly Size Images

Hi

When I run PageSpeed on any page on my website, I get the suggestions to “Defer offscreen images”, and “Properly size images” for the mobile page.

For example on this page

I have activated the relevant thumbnail sizes and regenerated all thumbnails, so I’d assume these should be used?

I thought AMP automatically deferred images too? Does the fact that they are part of a slider have something to do with them not being deferred?

Note I have tried this with all caching disabled so it’s not related to that.

Could you please advise.

Thanks,
Paul

Edit: It appears that the “Regenerate Thumbnails” plugin didn’t recognise the two mobile thumbnail sizes as registered image sizes. I uninstalled and reinstalled the plugin and now it’s generating the thumbnails. So my only issue now is the one around the deferred loadin of images.

Further update. Despite the “Regenerate Thumbnails” plugin, appearing to recongise the two sizes, it’s creating thumbnails called:

ppec_logo_image_size
ppec_header_image_size

rather than

td_265x198
td_741x486

Are the top ppec ones TagDiv thumbnails?

Hi Bettina

Very odd. I am using the “Regenerate Thumbnails” plugin in the link. Not sure why it wouldn’t be regenerating those two despite recognising the sizes.

Hi Bettina

I think it is something from the theme’s end not registering those two AMP td_265x198,
td_741x486 sizes properly. I removed all thumbnails from my server, deactivated all plugins except for tagdiv ones, toggled the option for those sizes to be active off and on again, and tried a few different thumbnail regeneration plugins. In all instances they didn’t generate for those two sizes despite them showing up as registered sizes, and in the instance of the “Regenerate Thumbnails” plugin, it generates ppec_logo_image_size and ppec_header_image_size instead (the other plugins don’t generate these two).

As for the defer issue, I think this must have something to do with the slider. On the AMP home and category pages I don’t get the issue, just posts where the AMP slider appears.

Sent thanks Bettina. I’ve combined it with the other two e-mail queries to keep it all together.

Hi @thecitylane, it seems that I’m having the same issue with those 2 mobile sizes not being registered as well. Were you able to solve the issue on your end?

Best,
Oz
