- Edit My Images
Well, posting direct from a DSLR to any media / website is quite difficult, but I presume you don't mean directly from the camera.Just posting an image from dSLR is near impossible
In which case actually, it is very easy to post photos from a PC to Instagram in just a couple of clicks using free (mainstream(ish)) software.
I'd hazard a guess that 30-40% of my posts are done in this way. I do use the flickr->phone->instagram route more though as I use the downtime of the daily commute on SWR.
