Hey in need of some help

 Ash:

how to insert an image in my tetx

I'm assuming you wanted to write Text. :)
Anyway, for adding images using the mdl text editor, you'll have to upload the image to an Image hosting site like postimages, imgur, etc at first. After that, copy the Direct image link and paste it into the Insert Image option. If you need further assistance, don't hesitate to ask :)

Yeah you can only upload pic or gif directly from ur phone or device in the feeds... There's a button to add the pic
