@Lordyaswas,
I keep seeing people say that - but I have never seen a 'quote' button and I use IE, Firefox and Chrome on Windows 7, 8 and 10 and Safari and Chrome on an ipad AND Chrome and the Samsung browser on android.
I always have to copy the image address (method differs wildly depending on OE) and paste it between the img tags the BBCode editor generates.
CI - if you are using Safari on an ipad touch the image and leave your finger there until it pops up with options
Save Image
Copy
touch Copy (copies the image address to clipboard)
In A2K reply all
in the BBCode editor press Img
Between the image tags
Code:[img][/img]
Paste (pastes the image address from clipboard)
Can be a pita getting the cursor between the image tags. I have a logitech keyboard on my ipad which has arrow keys and the cmd key which makes it easier.
