I've put together a website for my wife which displays photos of her craft
items. I take the photos and edit in Photoshop CS3. The photos are 72dpi
when opened in Photoshop. I'm not sure if this is right, but I've been
cropping each photo as needed and saving as 300dpi, and then resampling down
to the max allowed by the website host...which is 450dpi on the longest
side. This results in thumbnails on the website which can be clicked on to
get a larger version. I'm thinking that I don't need to resample to 300dpi?
Is this correct? The file size of each thumbnail is around 40kb or so. Any
advice appreciated.
Cheers,
Paul
The website is www.littleextras.net

then make a second 450 x 450 image and inport your newly edited photo
into it, making it fit, then use save to web option

Sorry, but rubbish! If you really want to know what the dpi of your monitor is
-- and I very much doubt if you do -- measure the screen dimensions, then divide
the total numbers of pixels by the dimensions. For my two screens the results
are 88dpi for one, and 96dpi for the other, in the horizontal direction. The
values are probably different in the vertical direction.
I don't know why Photoshop has its fixation with dpi, but the only time this
term has any meaning whatsoever is when you print a photo. Even then I generally
specify the dimensions of the printed image, and ignore the dpi altogether.
For anything to do with web pages the only significant quantities are the
dimensions of the image, in pixels (as Paul realised after he posted his
original message).
And, in answer to Paul's intended original question, the correct procedure is to
crop and/or optimise the image as required, save a copy in the original size (in
case you want to print it, or use it for some other purpose later), then
resample to the permitted size, and save, using the 'save for web' option. It is
not necessary to specify dpi at any stage in this process.

I was once told by a dude who worked with AOL and pioneered the 'gif' format
that monitors can't read beyond 75 dpi so take raw image hit ctrl > i >i,
change the dpi. Notice the dimensions change. Change the values to what you
want as long as they're not bigger than from where you started and
'constrain proportions' is checked, obviously.

The eye cannot recognize anything past 75dpi. Creating a high res image may
be good for print but to look at on a monitor is over kill

Yes it can.
