The text cant be changed (at least not by me). The maximum image resolution is set to 4000 x 3250 and the max image size is pretty much unlimited. There must be something else that I cant get access...

Does the link end with a valid image file type? (jpg, jpeg, gif, png, etc) quite often these shares are relative links and don't allow the browser to identify the file type that needs to be displayed.

I find Photobucket much easier to use. simple to get a fully tagged image link and I can also manage to post from my iPhone.
