ThumbsPlus has no problems with PSDs as long as you have the "Always
Maximize Compatibility for Photoshop (PSD) Files" option selected in
Edit/Preferences/File Handling. PSD files went through some major
changes after Version 2.5 (starting with Version 3.0). Most third party
programs will only read version 2.5 files. When you have the above
option enabled, Photoshop saves the image in both formats within the
file. That way other programs that normally do not read layered images
(what makes V3+ different), can open it. The disadvantage of doing this
is that your image file will be bigger than otherwise.

If you do not have layers defined, it is better to save these files as
TIFF as just about anything out there can read them while only a few
programs fully support PSD files. It is only advantageous to save an
image as a PSD when working with layers. Non compressed TIFF files are a
global standard. Everything worth anything will read it. The only
problem is when compression is used. There are many different ways to
compress a TIFF file and not all programs support all these different
formats. Of all, LZW is the most common compression method for TIFF
files. Even though it is lossless, it is usually of no use for
photography unless you have very large areas of all blacks or whites.
Compressing a "normal" photograph will result in a larger file than not
compressing it at all.

 
The advantage of using a program such as ThumbsPlus over Photoshop's (or
even Windows') "browser" is that thumbnails are created once, in one
place (a database). Programs that only create thumbnails on the fly are
useless for large image files while others that create "cache files" all
over the place create a nuisance as you end up with your hard disk full
of spurious files taking a considerable amount of space.

Subject: [Digital BW] Thumbnail views

I know there are a number of thumbnail viewer programs out there.
I've downloaded breeze browser for evaluation and it's fine but 
doens't view PSD files which is my habit.

Same appears to be true of ThumbsPlus.

Did I miss something?
I could see saving files as Tiff's without compression - don't know 
the consequences or difference from saving as PSD other than a viewer 
program could generate a preview.

Thanks,
Cleavis
