There's a saying in IT that you sometimes have to "eat your own dog food" in order to gain true empathy with your customers.
To that end, perhaps when raising a support ticket with Atlassian, you should supply screenshots embedded into Word documents rather than attaching the image file directly... just as we (paying) end-users of Jira Service Desk have to endure.
I'm going by the documentation for the plugin.
In this section, it seems you have to supply the project names the whitelist/blacklist applies to.
I couldn't find anything else on the same doc site that tells me how to whitelist/blacklist file extensions across all projects.
That's a completely different link to the one listed on Marketplace.
Additionally, from that site, it looks like the only option is global filtering, and there's no longer the ability to filter by project at all! This means, having a separate and more restrictive list for Service Desk projects is out of the question.
Not sure if you are still looking but I've developed a plugin called Document Vault (https://marketplace.atlassian.com/plugins/com.redmoon.jira.documentvault) which is a replacement for JIRA attachments. It gives you the ability to have a blacklist and whitelist of file extensions that can be attached to an Issue, including the use of regular expressions. Any current JIRA attachments can be hidden or included inside the Document Vault panel. You can also restrict access to attachments. I am also open to suggestions for other features.
