As the title suggests, I’d like all the images synchronized from Jira Cloud to Jira on-premise to be clickable.

Hello, Marcus Nygren ,
Thanks for the tip.
Here’s my script that is converting all the images into thumbnail-able images (replaces the given line in the incoming sync script on Jira on-prem):

//replace
//issue.comments     = commentHelper.mergeComments(issue, replica)
// withreplica.addedComments = replica.addedComments.collect { c ->
  def matcher = c.body =~ /!([^\|]+)\|([^t][^!]+)!/
  if (matcher.hasGroup()) {
    def m = matcher as List
    c.body = m.inject(c.body) { b, subMatch ->
      b = b.replace(subMatch[0], "!${subMatch[1]}|thumbnail!".toString()) 
      b
    }
  }
  c
}
issue.comments = commentHelper.mergeComments(issue, replica)

Here’s how it works:

Hello Serhiy,

The syntax for making an attachment clickable in Jira Server or Data Center is

!imageName.png|thumbnail!

If you alter the content of the field from cloud with a similar value, you should get a clickable image.

The syntax for the same image uploaded to a comment in cloud looks like this

!imagename (69707e93-425b-44d4-98de-950016f67c08).png|width=44,height=35!

The part between the pipe character and last exclamation mark on cloud can be appended with “,thumbnail” to achieve this effect. Turning it into

!imagename (69707e93-425b-44d4-98de-950016f67c08).png|width=44,height=35,thumbnail!
