Ok... first rule of web design, just because you can do something doesn't mean that you should!
Lose the music
Lose the random site theme per reload/page change
Second rule of web design - be consistent. Keep all the bits of the website alike. So put the effort in to make JAlbum look the same as the rest of your site or vice versa.
Third rule of Web design - Always check your language of choice.
"From buildings that have been left to rot and fall apart, to graffitti on the walls of our town centres." is not a sentence.
"To purchase prints is quite simple" should be rewritten "Purchasing prints is quite simple" - mind you I wouldn't use the word "quite" at all.
"Under the photograph in the gallery is four options" errrm how many options? 4? then "is" should be "are".
Rather than go through and pick holes in every sentence you have written (cos I am at work), I suggest that you get someone completely disconnected with you to read all the text on the website and fix the simple errors and inconsistent writing style. What I have seen so far isn't really professional and is certainly a long way from the 'Ultimate' in your website name
What do I like about the website? I do like the presentation of the pics on Black, though IMHO a neutral grey would be better.
