Thanks Everyone!
I am currently working on my first website. It will be as simple as
possible. I intend on displaying a few photos and I will have to digitize
them. What resolution is best for scanning the photos? I am of course
limited in my storage space but I assume the higher the resolution the
best quality images. Does anyone recommend a resolution?

Hi Patrick!
I keep my site to 768x1024 resolution, and scan the photos at either 75 or
100dpi. No higher.
Reasons for this are simple.
1) If you have hi-speed internet, download times are irrelevant and so
people who post tend only to think of image quality. But if files are large
(more than 35 to 45kb) loading times for dial-up users (the majority of the
world) quickly become more than people will tolerate and they leave. Lower
resolution and smaller image sizes mean faster loading. It's a trade-off.
Image quality vs. viewership. To me, it doesn't matter if the photos are
of the world's best quality, if nobody looks at 'em.
2) If your photos are truly good, there are people who will download 'em,
and sell the prints as their own. You cannot stop this, but by limiting
resolution, they can only sell lousy copies. It also saves storage space
on your ISP's server, thus allowing more photos on your site.
3) If your photos are good, it's wise to put a copyright notice on
'em. Note that by international convention, the copyright date is the year
they were first published (made public), not the year you took the
shot. Copyright lasts for the life time of the author plus 75
years. Again, this won't stop the serious thieves, but may dissuade some
amateurs. I use the Text tool in Photoshop for this.
4) to save double scanning, I usually scan at high res in TIF format and
then make a JPG copy, with the res I want, in Photoshop. Make your hi-res
scan, make all your corrections for saturation, contrast, brightness, etc.,
EXCEPT SHARPENING. Save and then make the low res copy you want. Then
sharpen the copy (unsharp mask usually preferred) and upload it.
BTW: You said: "I intend on displaying a few photos and I will have to
digitize them."
Fair enough... but if you find a way to display them on the internet,
without digitizing them, I want to be the first to know how you did
it! OK? '-)
Hope this helps. I'm looking forward to seeing your work. :)
Cheers!
