At the moment, as a non-customer, I am unable to view screenshots in a large format and can only view them as a thumbnail. This applies to the addon forum and possibly other forums. This is quite annoying as it would be nice to see what certain addons look like and how they have progressed, many administrators rely on addons to make their board more unique and can't or don't have the time to create their own work.
In my opinion this is very limiting, and very unhelpful especially in this example. I believe allowing people to view screenshots of addons may help motivate them to migrate/purchase xenforo as they may find an addon that works similar to (or better) than their current forum's setup.
I sent Brogan a message to find out what the reason behind this was and I was informed this was due to the fact all attachments are treated the same, whether they be .xml files or images. So obviously with the addon forum we are limited from downloading the products themselves, thereby also limited from viewing the screenshots.
If this limit was rectified it would obviously solve the problem for other communities out there who are being restricted by this.
I know the resource addon being produced may solve this however it would be nice if it was rectified for other forums who will not necessarily want to use the addon.
