I'm sorry, but I don't have a smartphone, so I can't help, either.
We have to have a restriction because we have limited storage. Another way to share pictures is if you don't do attachments, but link to pictures hosted on a different site, on Facebook, Flickr, Instagram, your blog, your shop, whatever it may be. If you want to do that and don't know how, I'll be glad to help, I'm just almost on the run at the moment and can't do it right now.
Glad you found something, Michelle, but if you want to have a look at it, I just updated the guide how to link to pictures on other sites (it was about time, too, since there have been some small changes ).
I just tried to post pictures using my Flickr site but they aren't showing up at all: when I hit the Insert Image icon the box appears, I paste in my link and nothing happens. Why is that? Is the site having problems?
