Batch thumbnail JPG lossless rotation that's much faster than Irvanfiew

Irfanview is so slow as to be unusable when rotating JPEG pictures in
folders containing many hundreds of large-size digital photos that I ask if
there is a faster lossless rotation program out there?

The use model would be similar to what Irfanview does in batch mode:
a. View the thumbnails (as many as can fit on a screen)
b. Control-select the thumbnails that require 90-degree rotation (scroll
when necessary)
c. Press the 90-degree lossless-rotation button when ready

I love Irfanview, as do most of us, but, the batch lossless rotation is
frustratingly impossibly slow (all that repainting for nothing).

I ask ......
Is there a faster thumbnail-select batch lossless rotation freeware?

Not yet tried lossless rotation as most its features there,
but recently I downloads free FastStone image viewer.

Even if like Irfanview, in some aspects FS seems
at least as much as good. And, it has lossless rotation too.

If not tried other faster LL JPG rotating program,
how do you know Irfanview is slow ? :-)

What if lossless rotating IS slow ?

It isn't the lossless rotation that's slow in Irfanview.

Irfanview is great but in thumbnail mode, with 500 large pictures, and you
rotate just one, Irfanview tediously repaints all 500 thumbnails.

That's what's slow. The repaint of 500 thumbnails when only a few are
changed.

Or, as workaround,

selecting images to rotate,
use move feature
close IV in case it wants to repaint the rest.
Run IV Thumbnails over folder with chosen images
Perform rotation
Move them back

OT here:

I, as photographer, do not see much sense
in keeping 500 images in the only folder.

I would either divide them either
according to time, or topic.

Or, if monolithic,
then probably bigger part can be deleted.

I almost never use thumbnail view in Irfanview. My method for lossless
rotation is shift-J <enter> while browsing. I wasn't aware that could be
done in batch with the thumbnail view!

Not off-topic. Any program is bound to struggle with 500 images in a folder.

Ah, you understand the problem!

Today, when I have a lot of pictures to losslessly rotate, I put Irfanview
in thumnails and then select, one by one, a hundred or two hundred pictures
to losslessly rotate in thumbnail view but if I misclick just once ...
auuuuurrrrrrrgggggggghhhhh, I have to start all over again.

To save me from the invariable misclick loss, I would only click on, say,
50 or so pictures to losslessly rotate ... but then I have the inordinate
wait as Irfanview painfully redraws all the thumbnails in the folder, not
just the 100 or so that were losslessly rotated.

IrfanView is great but I might just not use the thumbnail view lossless
rotation selection process and just do it manually like you said, to the
whole folder. At least then, the SELECTION process is simple and watching
the repaint of thumbnails can be stopped or just let run to fruition, once,
thank God.

Actually, when I use cameras like my last broken Nikon which save EXIF
orientation inside the picture, then Irfanview AUTOMATICALLY losslessly
rotates all 500 pictures (as needed) in a single step!

For that, the IrfanView use model is simple!
1. Take picture any way you like (90 degrees, 180 degrees, 270 degrees)
2. Open a picture in IrfanView and go into batch mode and wait for repaint
to finish (always slow in Irfanview when you have 500 pictures)
3. Select all pictures and run a lossless rotation based on EXIF
orientation & reset the orientation within Irfanview on all 500 pictures,
all in one fell swoop

Maybe the solution is to go out and buy another camera that automatically
stores EXIF orientation information in the photograph but I'm sick and
tired of the cheap Nikons breaking under load (but that's another OT
topic).

Exactly. Poutnik knows what hes talking about!

The refresh takes far more time than the lossless rotate, at least in
IrfanView 4.22 on WinXP.

I'll try Fast One's lossless rotation .... but boy oh boy, Irfanview is so
fast and good in everything else I need that I hate two switch products
without trying for a solution (thanks everyone).

Mention it to the developers, maybe they'll fix it in the next release.

But, aside of IV problems,

I still think best is avoiding of so huge folders,
as I posted before.

Hi Poutnik,

My use model is to have a folder for each time I dump the pictures and
movies off my HDSC camera card.

How many pictures that is is exactly what I've taken on the card.

I guess I could separate the folders by some other mechanism but I've been
using this method ever since digital cameras came out and it seems logical
to me.

It was working fine with Irvanview when my Nikon was putting orientation
information in the JPEG EXIF information but I broke my Nikon (I've broken
four of them in the past six years ... sigh) and now am using a Casio that
does not put EXIF information into the JPEG headers.

So the problem only recently came up because to autorotate all pictures in
IrfanView is not nearly as cumbersome as to rotate only the selected
pictures due to the way Irfanview paints the thumbnails over and over and
over again.

Again, I don't fault Irvanview; it's a great program; I was just trying to
rotate select pictures out of hundreds in a folder.

Just move those pictures to a work folder, rotate, then move back. Or
better yet, process them in pieces, moving only a few into the work
folder at a time for thumbnail display.

It is what I was advising dome posts before.

Maybe try XnView. You can do the same thing, thumbnail mode, select
tham all or whatever you want, Tools->JPEG Lossless
Transformations->rotate [90 left, right, 180, or based on EXIF]

It doesn't redraw the thumbnails until it's finished rotating them
all.
