RIPPING OFF WEB SITES
Thieves are downloading the source code of Web sites and reselling
the unique elements.
Digimarc, which comes as a third party addition in Photoshop 4, is able to put a
digital watermark on your material and Digimarc says they will be sending a spider
around the Web to look for pirate uses.
__ However, Digimarc's services are expensive, and even
if they do find illegal usage, it is prohibitively expensive to sue for copyright
infringement in the US and virtually impossible to do so overseas.
HOME PAGE TIPS
Mistakes I made while redesigning my Earthlink Web site taught me a lot, and I would
like to share what I learned.
- Some compression programs have changed from appending ‘jpeg' to appending ‘jpg'.
This is not recognized as the same name when you upload a replacement file to your
web site. If you do not want to redo your links, just change the name to agree with
that of the original file.
- If you upload a replacement file with jpg instead of jpeg, or vice versa, the
new file will not replace the old one and the old file will remain in the folder
on your web site. Since a site with a lot of pictures can easily put you over the
2 meg home page allowence (I know!), you don't want old files consuming space.
- Earthlink has a really excellent new facility. You go to their special address
for the purpose, type in just your e-mail address and within a couple of minutes
a complete list of your web site's file names, dates and sizes, the size of your
web site folder, as well as the site's traffic in downloaded megs for the month,
appear in your e-mail box. This provides a perfect way to check for redundant files
and old files you are no longer using.
- If you change the dimensions of an image, then just upload it as a replacement,
it will be distorted to fit in the dimensions of the place held by the original image.
When you change the dimensions you must make the replacement by editing your html
page. This does not apply if the dimensions of the image stay the same but you change
the number of kilobytes by increasing or decreasing the level of compression you
use.
- For reasons of both space and download time, it is important to compress your
images as much as you can without unacceptable sacrifice of quality.HVS JPEG, a Photoshop
filter that compresses files and exports them as jpegs, gives you many controls over
the look and amount of compression, and has a preview window which I couldn't work
without.
Important note: The name that comes up in HVS's Save window is not that of
the file you are compressing but that of the last file you compressed, so be sure
to change the name, or the new file will overwrite the previous one in your folder,
and have the wrong name as well.
