Ok, I've tried linking to the image file on an image storeage site - won't work. Copy & pasting it into a post does not appear to be possible, not surprisingly. Done a 'Search' using every combination of words I could think of, just gets me to other people's uploaded image files. I did try to find out before posting, honest !
I would really like to just upload it from my computer, but I gather that's not possible.
So how does one insert an image file into a post, please? Many thanks!
Sorry, sorry! I just found it. Just IMVHO, it is difficult to spot. And when its only available when in reply mode. Anyway, problem solved!
