with regards to customizing banners for use on the rotating banners on dew-new phplinks...
(1) go to the root directory of your directory install...
(2) find the "banners" directory/folder
(3) add or remove banners files (0.html through xx.html)
(4) banner html files can contain whatever kind of php, flash, javascript or just good ol' html code in each file, I have even gone as far as piece mealing together a random Q&A panel which used php to call up records from mysql tables...as one of the *.html pages that came up as a "banner" on my site.
(5) if you need resources for setting up your own banners (advertisements that would fit well for the niche or content of your site) check a few webmaster resources for generating add funds like:
...the 2 above sites (which are not associated with or are not endorsed by this dew-code.com site) are at no cost [pretty much FREE] to a web publisher (except maintenance) and can potentially generate some income for you if you can drive in traffic to your site...SEO is another topic however.
The other pice of the code that you should keep in tact (besides the "powered-by" and one of dewed's adsense banners is the thumbshots tagline..."Free Website thumbnail previews by Thumbshots.org" or however it reads...
