I followed Tutorial: Using an Amazon S3 trigger to create thumbnail images - AWS Lambda to create a thumbnail for my images.

However, when I try to access the images in bucket-resized I get an Access Denied.

CodePudding user response：

That tutorial does not create 'public' objects.

If you want the resized objects to be public, you would either need to:

• Create a Bucket Policy on the 'resized' bucket that grants s3:GetObject access for the bucket (see Bucket policy examples - Granting read-only permission to an anonymous user), OR
• When uploading the object, use ACL='public-read', which will make the individual objects public

To make the bucket or objects public, you will also need to disable S3 Block Public Access on the bucket.

CodePudding user response：

1. check if the thumbnail is generated successfully
2. check your bucket has public accessibility enabled
3. check if the generated file thumbnail has public read permission
