"save as jpeg" vs. "save for web"

I just tried to upload some of my photos to Photonet but they were rejected!
I was told that the reason why is because they weren't created using the
"Save for web" protocol! The original scanned images were "tiff's" and I
saved them as jpg's, not realizing that "Save for web" was any different
than a "jpg" file, does this mean that some browsers won't be able to view
these images on the web, or what exactly does it mean?

Thanks all!

 

A JPG saved through the SFW feature is the same as one saved as... a jpeg.
The major differences in the SFW function are the comparitive displays and
the ability to store settings. Otherwise I can't say why the Photonet
service doesn't allow you to save the file. Post the file up here if you
want us to look at it.

No, don't post images in this newsgroup.

 

'Save for web' strips the image of anything you don't need on the web,
such as EXIF data. These data make the image larger than needed, and
that is probably the reason why Photonet scans for EXIF data and rejects
images that contain them. Save for web is not different in any other
way; it's just an ordinary JPG (or GIF).

 

Ray,

The JPG format can save images in CMYK colors for printing, as well as RGB
for on-screen display. A CMYK TIF can be "Saved As" a JPG, but will not
display in most browsers. Be sure it has been converted to RGB mode first.
