You can delete any image you've created directly from Samsa.
You'll find the delete button (trash icon) in several places:
Gallery — hover over any image to see the delete button
Image viewer — in the action bar when viewing an image
Favorites — hover over a favorited image
Edit history — hover over any version in the timeline
When you click delete, a confirmation dialog asks you to confirm. This helps prevent accidental deletions.
If you'd rather skip this step, check the Don't ask me again box.
The image is permanently removed — this can't be undone
It disappears from your gallery, favorites, and any projects it was in
Other versions and variations are not affected — only the specific image you delete is removed
You can only delete images that you created yourself
In a team organization, you won't see delete buttons on images from other members
