avatars are being deleted after thumbnail regenarting

[ituk]

after regenerating all thumbnails in site and wiping unnecessary images (using Regenerate Thumbnails plugin), some avatars thumbnail where deleted. so...

1. is there a way to regenerate them? the original files are still there, only the cropped ones are gone.
2. there must a be a way to prevent things like that from happening. maybe registering the avatars as image_size?

@ituk I believe they should be regenerated on demand when that specific size is requested; are you seeing broken avatar images on your site or just that specific file sizes are missing in your "uploads" folder?

[ituk]

thanks @jeffpaul, but i only see broken avatars. i managed to restore most avatars from a backup i had, but i guess the core of the issue is still there.

@ituk thanks for the update. Mind confirming your environmental info to help us triage this and aim for a resolution in the 2.2 milestoned release?

I can reproduce this problem. The cropped avatars get deleted by Regenerate Thumbnails but the simple_local_avatar user meta still exists. Simple Local Avatar gets avatar data from that meta first, then if it doesn't exist SLA will generate a new avatar from the original file.

there must a be a way to prevent things like that from happening. maybe registering the avatars as image_size

This will do the trick. By registering an image size, the avatar will get regenerated like other image sizes.

Btw, we still need a way to clear the avatar cache (saved as user meta).

[dinhtungdu]

Here is my idea about clearing the cache. The only place I can think about is under Settings > Discussion. But IMO, that's not a good UX because we go to setting to configure the plugin, not clearing cache or taking action.

@dinhtungdu as we're still working on crafting the approach here, I'm going to move this out of the current milestone so we can move more quickly towards releasing version 2.2.0.

I'm also running into the issue of missing profile image. Try to implement a way to catch this before user start complaining. Is there some way to do this? I try to call get_avatar($user_id, 70) for both user with/without uploaded image. And the output is always returning the image from gravatar.com url not actual local image url.

something like:

string(257) "<img alt='Avatar for ' title='Gravatar for ' src='http://2.gravatar.com/avatar/?s=70&#038;d=mm&#038;r=g' srcset='http://0.gravatar.com/avatar/?s=140&#038;d=mm&#038;r=g 2x' class='avatar avatar-70 photo avatar-default' height='70' width='70' loading='lazy'/>"

Hi @dinhtungdu I am starting to look into it, I am not getting where the image sizes are coming from to add it as an image size so it is generated on regenerate, also what changes is the Clear cache meant to do?

[dinhtungdu]

@thrijith I'm sorry for this late reply! The avatars are generated on the fly so there isn't any image size to register. The cropped avatar URL is stored as the user metadata. After regenerating thumbnails, all thumbnails are deleted including ones cropped by Simple Local Avatar. But the URLs in the user meta aren't deleted, that's why we have the broken avatars.

The idea behind the Clear cache button is to delete all cropped avatar URLs in the user meta and the respective avatar files.
