Well, I didn't pretend GIMP was THE definitive solution to all
problems:-)
<br>
My comment was rather to point out an alternative to Gwenview.
<br>
And, as usual, the best tool for someone will deeply depend on
what you
<br>
expect to do with. But I can answer to your objections :

Synchronisation, you're right, this requires a single partitionned
<br>
window to handle that. With a "any windows number" tool, you don't
get
<br>
synchronisation. But you're not stuck to 2, 4 or 6 images at a
time.

Gwenview: contol/shift click in thumbnail bar and to select any
number of pictures (up to 6 I beleave) to compare, rightclick
synchronize, control left click to zoom in contol rightclick to zoom
out, move sliders to sychronuously move around.<br>
<br>
More than 6 looks quite pointless, select the best and add 5 new
ones and select the best again.<br>
This could be copied not improved. <br>
Digikam and Gwenview makes a perfect match for me.<br>

Memory is not a software related issue but a computer issue.
<br>
Whatever tool you use, the max number of images you may be able to
handle
<br>
at a time will depend on your computer RAM and swap.
<br>
If you can't open 10 images with GIMP, you won't open them with
Gwenview,
<br>
or anything else, at least on the same machine.
<br>
(And swap memory is not a solution, it's too sloooooooow)

<br>
RAW image ? Was that the initial issue ? I don't know raw images
viewers,
<br>
or multiple raw images viewers, just raw images processors.
<br>
When I try to open with GIMP one of my .NEF file, GIMP fells back
to
<br>
lauching ufraw (it's my KDE file association).
<br>
If I try to open it with Gwenview, I just get an error message
<br>
"cannot display documents of type image/x-nikon-nef"
<br>
So...

As for "compare side by side", it would probably require to define
what
<br>
is "compare", what kind of comparision is awaited ? To have a
global look
<br>
on similar images, composition, general coloured atmosphère,
having
<br>
windows side by side is the same as having images side by side in
a
<br>
single window.
<br>
In some other cases, images side by side will give nothing.
<br>
E.g. you wish to compare similar pictures (same subject, shot in
the
<br>
same time interval) taken in low ambient light and at low shutter
speed,
<br>
say 1/30 s or 1/15 s, and you suspect you may have some focus
defects
<br>
due to slow speed and hand held camera. Side by side will give
nothing,
<br>
exceptt if out of focus is obvious (and the image can be garbaged
at once).
<br>
To do that kind of comparison, and as I'm a GIMP user, I select a
small
<br>
area of each picture with fine details, and copy/paste into an
empty work window as layers. Layers can be superimposed, switch
on/off one by one,
<br>
it's possible to make one layer half transparent and compare with
the
<br>
underlying one on really small details.
<br>
It becomes possible to have an accurate idea of the best focused
shot,
<br>
but it takes a bit more time than just "have a glance".
<br>
<br>
<br>
But as I said above, there's never a definitive solution and each
user
<br>
will have his preferred "modus operandi". Different software are
never
<br>
stricly equivalent, so probably each user should test and try such
and
<br>
such program, then select the best suited for particular needs.
<br>
I believe the question is not to decide which program is the best
<br>
(the answer will always be : hem, it depends...:-) but what can do
<br>
such or such program, can do very well, well, not very well, not
at
<br>
all, then let users choose according to their needs.
