Providing they're not too large and jpg's - I've not had any trouble uploading pics. But I've only ever been able to load one at a time. So, I
signed up for a free image hosting website (Image Shack) - upload my pics to that, then hit the 'picture' icon and put the direct link in - that way I
can put a heap of pics in one post. For a single jpg from you computer, are you using the 'choose file' attachement at the bottom of the page? If
so, your pics may be too large....
