When you upload your images, ensure that the filename has no spaces in it - simple !!!!
I have trawled the forum but am unable to find anyone else who has had the same problem - so is it just me? I also cannot find anything in the documentation regarding protocol for filenames - have I missed it? Is there a fix regarding this which can be introduced during the next version update or tweek which may prevent other users having the same problems as I have had - I would be interested to find out!
