Hey Paul, if you dont mind it being
really simple, and if you have CS already? (I think the last two had it too from memory?) and its not a heavy text based thing, just simple galleries. Try menu file>automate>web photo gallery feature, existing templates can be modified with a simple html proggy if you wish (after copying), but it is kinda flexible already.
A hand full of templates to choose from in styles, and use options to change anything that is changeble, which is quite a bit.
just make sure you select extension> html in options>general when naming file
point it to a folder of pics and hey presto! fast and very neat
use your browser(s) to quickly check out results

save the folder and upload it (to free your ISP account user webspace I am assuming?) still need a little free ftp proggy to do that, of which there are many -
i dont use web photo gallery - have played around with it, , but I have few mates that love it for a really quick clean gallery page of their kids BD parties or whatever ect.
