I'd say just use Photoshop to design a nifty looking web page and be done with it. Shouldn't take ya more than evening.
Make some small versions of the pics you want to display for use as thumbnails. Then design a page layout using those thumbnails. Use Photoshop's Slice Tool to define where the links are (the thumbnails) that will take the viewer to the full size images. Photoshop will automatically slice up all the undefined space for you. Then use the Save For Web feature to output it all to images and an HTML document that will use a table to put all the images together like puzzle pieces and make your web page. Couldn't be easier.
The
Simon the Cat page that you've seen before was done like this. Took me maybe an hour. And of course it doesn't have to be as goofy as my page is, you could easily use the same technique to do something more sophisticated.
