Hi Ros,
Hmmm strange. If you tick the little box that says 'Log me in automatically' you shouldn't need to log in at all when visiting from your computer because it remembers you.
This only works though if your security settings on the computer browser can accept 'cookies' (the small file that is saved to your computer to remember you).
When logging in the first time, are you typing your username / password in and does it say you have an incorrect username or password?
And finally, what browser do you use? Internet Explorer?
With the photos, I had to set a limit on the size so they don't go off the screen. The whole image thing is a bit of a pain and I am hoping to find an easier / better resizing solution sometime that could work on the server with the forum software and resize them automatically. I'm always cautious with installing add-ons though because they can have bugs that cause problems.
Let me know anyway and I will see if I can find out what's happening.
Tim
