Cannot upload images

I can't upload photos to my squarespace blog and it's driving me nuts. Yes I've tried to make the files smaller. It still just shows an error message. The formatting for the blog is also messed up. How do I get in touch with someone at Squarespace or get some help with it? 

Squarespace don't routinely monitor this forum for issues (see the guidelines - item 6) so I recommend you contact Squarespace Customer Care directly to ask for help.
