Can I stop Batch Processes from Compressing jpegs like a Jerk?

When using a simple "resize" script for a batch process, the script runs
fine and my batch is resized, BUT the pictures are way too compressed! It
squishes 1200x800 photos down to a measly 150K! That looks so bad... is
there any way to change the default compression for the saves that batch
processes make?

In regular photo shop saves, my default/last used compression is factor 1
(lowest compression, highest quality.) So it isn't taking it's orders from
that.

I've tried recording a "trusted" script where I save the file at my
preffered compression value, and then running a batch process on that... but
that doesn't work. It still compresses my pictures to it's own mysterious
tastes! Is there any way to change that?

Thank you very much for reading my question

There is no default compression to change. PSP remembers its last
settings for JPEG encoding: compression, chroma sub-sampling, save
EXIF data or not, and standard or progressive scan. Set these once
before running your batch. The easiest way to do that is to run File

See the button beside the 'Save'> 'Type' labeled 'Options'?

Let's start with a simple question about what you are doing that
you haven't told us about. To open and save files are you using the
capabilities of File > Batch > Process or do you have File > Open
and File > Save As commands embedded in your script?

Nobody cares what happens in Photoshop. This is Paint Shop Pro and
it doesn't take any interest in what you did in Photoshop. In Paint
Shop Pro using compression levels much below 10 (e.g. 1) is pretty
pointless since it doesn't save much on file size and you might as
well be using a lossless format like LZW compressed TIFF or PNG.

Don't do your own file handling. Instead do File > Batch > Process.
Select JPEG as the output type. Press the Options button and make
the desired settings. See attached.

Hmmm. The install default on my 9 was JPEG=20 which does
indeed destroy my precious car pictures I don't know the
version number in question nor other default(s), but if the
OP never changed it, that is the explanation. PSP does
indeed remember, including its install defaults. How do I
know this? Because I had the same exact problem trying to do
exactly the same thing. Among others, Ron Vick discovered
this and other dumb things I'd inadvertently done recording
the script and quickly helped me. About the only thing I
might have suggested to the OP is to not be quite so, er ...
graphic in the subject line.

If you realy did mean Photoshop then 1 is the highest comprestion in that
programe.
