multiple thumbnails getting created

[PoulomiB]

how to stop multiple unnecessary thumb creation in sys_attachment table in UI16. sys_properties: glide.ui.activity_stream.scale_images is set to FALSE as mentioned in KB KB1923362 https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB1923362

Hi Buddy,

Try this 1st:

1. System Definition → Business Rules

2. Table = sys_attachment

3. Search BR scripts for: thumb, thumbnail, scale, image

4. When you find the rule generating thumb_*:

   • Disable it, or (safer)

   • Add conditions so it only runs where you truly need thumbnails (specific tables like sys_user photos, knowledge images, etc.)

This is the only reliable way I know to stop multiple unnecessary thumb creation at the source.

Hi @PoulomiB 

Currently, we are in Next Experience, so I don’t think this property will work. It would be better to log a Now Support case so the team can help you.

If it is still valid, try clearing the cache and test again with a new attachment.
