This is a simple image tool to resize pictures and optionally add a watermark.
I created it while building my personal website — to make large scanned images smaller for faster loading, and to protect content with visible watermarks.
Of course, CSS can also overlay a watermark visually without altering the image itself. But if you want the watermark embedded directly, this tool is for you.
It’s open source, so feel free to modify it for your own needs. https://github.com/Zoe-B-Zhang/misc.git
