Hello, I already researched several sites and found nothing about it. Can you access the image information (exif) and remove it with the Corona SDK?
You need to sharpen your Google Foo. 
I searched for “Lua EXIF”:
- Found many sources
- Grabbed one randomly: https://gist.github.com/duckfly-tw/7c3c453012906321cb00d63b12ba0711
- Modified it
- Tested it: https://github.com/roaminggamer/RG_FreeStuff/raw/master/AskEd/2018/05/exif.zip
It works to read, but the sample only extracts some values, there are many more it could extract: https://www.media.mit.edu/pia/Research/deepview/exif.html
Modifying and extending it to read more data, ** plus to **modify the data, plus to write back shouldn’t be too hard, assuming you know about EXIF data format rules.
