authoring: how do I delete custom thumbnails once I upload one?

Avatar

Level 8

i cannot see an option to delete it. (The delete feature has to be available via touch/classic UI as our authors don't have access to CRX/DE)

 

I tried generate preview and the generated image is a preview of the page itself and not the original image that was there.

@jayv25585659 : There is no option to delete it once you have provided a thumbnail. However, you can update it to restore to previously used thumbnail by below options I assume:-
Select Image - You can select the original thumbnail by choosing this option and select the original thumbnail image from DAM.

Upload Image - You could upload the original thumbnail by choosing "Upload Image".
If you were in middle of making changes and not happy with what you have selected, you see a 'Revert' option to un-do the changes, but that is until you have not saved your changes.
Please refer this to see the options to configure page thumbnail:-

Unfortunately, the AEM does not provide a direct option to delete a custom thumbnail from the UI, you can remove the thumbnail from the system through the CRX/DE. This is because when a thumbnail is uploaded and used in the UI, AEM automatically generates different sized thumbnails, stored in thumbnail.png/jcr:content/dam:thumbnails. Even though the parent thumbnail.png is updated, these generated thumbnails remain the same.

The only way to clear them out is to go into CRX/DE and delete the dam:thumbnails folder. Then the next time the thumbnail is used in the UI, it will be recreated with new images in it.

@jayv25585659 You can extend the OOTB DAM asset update workflow and add a custom process step to clean up any specific thumbnails. as soon as the asset processing is done, your custom process step should take care of that.
