If you're dual-wielding a Unique item, please indicate it has been transmogrified in the caption. Thus, if you have a Training Sword transmogrified to look like the Corrupted Ashbringer, you would submit the shot to the latter's entry, not the former. For Transmogrified items, the rule of thumb is the screenshot should match the model of the item's normal appearance.It also doesn't thumbnail well, and can't be adjusted for different languages. The reasoning is it's usually redundant with the information already provided in the entry. We make the occasional exception for joke screenshots, titles, and NPC dialog, but that's it. Press Alt+Z to dismiss most of it, but you may have to turn off names as well. ALL OF IT! No targeting circles, no names, no addons, no damage/heal numbers, no maps, no bars, no chat windows, no target icons, no GM response windows, no interface elements of any kind. When you're submitting gear shots, focus on the gear piece itself, rather than the character wearing it. Usually, your subject should be roughly centered (both vertically and horizontally), with some framing scenery, but not too much. CROP! Don't submit the whole screen if you're just trying to take a picture of a pet, mount, or something your character is wearing.Screenshots from official beta servers are fine, though they'll be removed, or note added, if the models change. If we catch you doing it too often, we'll just remove your ability to submit them. We don't always catch them, but when we do, not only will we reject them, it makes us very suspicious of all your future submissions. Don't submit screenshots obtained from private servers, sandboxes, model viewers, the dressing room, etc.
