Hi there. I've used K2 for years and love the flexibility especially with tags. Recently, we are moving to more front-end publishers coming on board and we need to make front-end publishing as user friendly as possible. I actually installed joomlart's iJoomla Publisher pro because of how nice the front-end submit article screen is. SPECIFICALLY how you can use and view your own media/images I want to continue to use K2, is there best practices documentation for front end publishers? Are there some free or paid k2 extensions that would make this experience better? Any advice would be greatly appreciated. Thank you.

PS: I tried to attach a screen shot of the funtionality of publihserpro that I need to get close to but the attachment button didn't work for me (in Chrome) Here is a direct link (demo/demo) So I need to get my front-end K2 as close to THIS as possible
