Yep, I think that would be a problem but then they can always regulate the frequencies wouldn’t they?

Here is an addon by Torstein Hønsi for creating sharper thumbnails. Simply paste this function at the bottom of the existing script and call it just before the last line of the existing script like so..
You can change the parameters as you like.

first of all - great script! really liked it..and i keep using it on all of my sites!
i have a question, i have a watermark script which i refer to as wimage.php?IMAGE.JPG and it adds a PNG based watermark protection.
now, when i refer imgresize.php?w=100&h=100&img=http://www.FULL-URL.com/wimage.php?SomePhoto.jpg it works great, i mean, its a full combination of 2 scripts, first it puts watermark and then it resizes it. the problem is that it takes too long because of the re-calling for the images. i am trying to access now imgresize.php?w=100&h=100&img=images/photos/SOMEPHOTO.jpg it gives me an error. how can i combine these two scripts? or how can i simply add a watermark protection (PNG based) to this awsome script???

because in SmartBro there are like 10-20 people sharing the same IP addresss…and with opendns it is IP related meaning every setting you made with opendns (like adult filtering etc.) it will also affect other people who share the same IP with you, especially if that person is also using opendns…
