No permission to buy ($31.82)
@truonglv worked with me in regards to app. It installs with zero issue and watermarks images as requested. Thanks for your help!
I'm the first customer, so far so good, the add-on works as expected. The add-on is working with S3/DO space file storage from Chris D's add-on, good for storage files with no worries about disk space if you're running with a large forum
The author also good in support for fix issues if it happens, worth for 5 star :), that's my experienced for this add-on and the author truonglv
PERFECT - installed with no issues, adjusted settings and tested. Results are exactly as expected. I wish we could make it affect all old attachments.
