Multiple WEBP Conversion Script with Recursion
Hi All I've tried getting help on this in multiple places in the community but I think I'm posting in the wrong places. So I'll try here in a new post.
I've taken 2 scripts created by @Stephen Marsh and combined them. The first is a script he wrote to convert files to WEBP and the second is a script with recursive folder process which was created to resize existing WEBP images.
For the most part my hybrid seems to work fine but it's failing when processing smaller images whether this is dimensions or file size I'm not entirely sure.
At first I though this was only a PNG issue so altered to skip them but the problem still exists.
If an expert could take a look and help I'd be so grateful.
