What should be the setting if one is not using the default us data center?
Thanks nice post
Thanks,very nice post. Append folder name to $actual_image_name then it will put the file to FOLDER.
Will this be a direct upload to the server, or moving it from temp directory to the server?
Great Job
Great job, my only work is to rename the folder
Will this be a direct upload to the server, or moving it from temp directory to the server?
In my bucket I have a folder, I want to upload the file to the specific folder within my bucket, how can I do that?
In shared hosts running Apache + PHP, the maximum file size to upload will be fixed by 'post_max_size' or this rule will be bypassed?
"In shared hosts running Apache + PHP, the maximum file size to upload will be fixed by 'post_max_size' or this rule will be bypassed?"
Looks like s3 is not even called for until the file size is checked. This means you should be limited to the php.ini max size. Fill me in if I'm wrong.
Very Nice Tutorial,
I am using this exemplo to upload my images.
I have only a littler question:
I am try to send to S3 some resize images. I send the original photo and after I need to resize this image and send to S3 the resized images.
How can I resize a image and send to S3?
