Hi Mike,
Okay thanks, I'll take a look at the other methods. I used to use the original uploader for quite some time (years I guess), and then at some point about a year ago there was an ongoing problem using it with Macs in OSX. So from then on I have been using the html basic uploader - which is a slower way to do it, but it worked. I'm not quite sure for how long I've been doing that, but some months. I lose track of time sorry... I haven't used the most recent uploader program, so I might try that.
For whatever reason, I have noticed a difference in my image quality for about the past three months or so. Might be a bit longer even. I'm not sure why or what that would be then. I will try the new uploader and see how that goes. The original uploader program has a long out of date security certificate, so I'm a bit hesitant to use it - considering it uses java to access my computer.
I'll try some of those options and see how it goes, otherwise I'll try something else.
Thanks for your help and clear responses.
Ash
