I have managed to access some images now and PS opens up when I click on the edit image button!
A different issue (should I open a new thread?) is that in MANGING COLOURS:
WHen i try to change a colour within an html table it doesn't change it - it doesn't even show in the preview page. I know it can SEE the table colours, because they appear in the colour listing. Shouldn't it work ok and show up in the previes page...?
