What's the context? You probably don't need a regex. You can do the lot with a few replaces. A lot easier to read for those that don't do regex's. Probably not as efficient as a rgex but it works, and unless you're doing millions of calls to this in one go, the efficiency will porbably not affect you.


function fixFileName(psFileName)
{
  return psFileName.replace('https://d1yl1kh78jj1rr.cloudfront.net/thumbnail/', '').replace('_M', '').replace('_thumb', '').replace('?response-content-disposition', '');
}

I need a regex, the system I use requires a regex input to do its processing.

please note that the regexr site shows only first match from the whole string, so if you paste all of the URLs in the regexr only the first will match, you can delete one by one and see if the next one matches - as you would also process each line by line
