hahahahahahahahahahahahahhahahahahahahahhahaha!
sorry, just had to laugh.
yeah go on slice all 28pages, realise how frustrating it is, how time consuming it is, then take it to the client who will then say oh actually I like this like that, and like that, then go back to photoshop and do the whole process all over again....only to have another change and again do the whole process again.
Only then will you have this niggling thought in your head that is saying "surely there is an easier way to do this"...
When you are ready to listen to that little voice, listen to it because it will whisper three letters to you...
C. S. S.
and when you learn CSS you can then go back to whoever it was that told you you had to design in photoshop then slice it to make good web designs. tell them that they are an idiot and continuously punch them in the head.
I must admit I find teachers of web design the worst because they still teach this junk.
I have a full time job building websites and for the past 5 years I have not once used a psd design. not once and I can tell you it makes the whole process a hell of a lot easier. the only time I use photoshop is for resizing images, and saving them for web. most logos I will use illustrator, and everything else is css.
but pixel pusher is right if you HAVE to use this totally outdated technique then the best way would be to design a template...
