Resolutions of 72dpi and 96dpi - why ?

[spirit webforumsuser@macromedia.com]

Most of the time my final exports of jpegs and gifs are 72dpi. But every now and then I find that they're 96dpi.

Why ?

I really don't want to have to go back and check every time I export something (dozens every day) but I can't figure out why this happens.

On the other hand it doesn't seemt o make any difference to the artwork....

Very puzzled.

Are you maybe importing from another application? I notice that SnagIt
seems to use 96dpi. If I collect a screenshot to the clipboard using
snagit, then paste it into a new FW doc, the default is 96 dpi. This can be
changed when the new document is created, at which point the pixel count is
whats important to retain.

For display purposes it really doesn't matter... 1 pixel is 1 pixel, however
if you're working with something that might be printed (eg a web page), then
you should use one or the other so that they are proportional when printed.

GIFs do not store any resolution setting at all. It is just not the part of
the format specs. So, if you think that your GIF have some particular
resolution - this is nothing but misunderstanding.

JPEGs can store resolution info. However, this info has nothing to do with
the way JPEGs are displayed by web browsers. Browsers show one image pixel
as one display pixel, that's all.

If the "artwork" is something to be displayed on the display (sorry for an
oxymoron), then resolution makes no sence at all. One image pixel takes one
display pixel, that's all.
