Try gThumb.......................

Try Picasa - it's great for tweaking and resizing through the 'Export'
function. Needs a bit of 'trial and error' to get file sizes to a
certain level but if you want more control over that then 'Gimp' is
what you'll need and 'Save As'.

DigiKam is the best programme for this without going to the GIMP which is a
full blown editor. I would also look at Krita and Shotwell. The first two
are parts of KDE but work in Ubuntu (GNOME) just fine. Shotwell has replaced
F-Spot in Ubuntu 10.10, but it is alaso available for Lucid. You could try
Picasa, but it is not a native Linux application. It uses Wine libraries to
work and it can be slow, IMO. There is also a Nautilus action that you can
add in the repositories that will do this from a right click in the file
manager.

Got digiKam and gThumb and they both look good. I think this'll do
it.

I know that many GNOME users are reluctant to try KDE applications, but
there are several good ones that are better than their GNOME counterparts.
For years GNOME has included F-Spot, but it trashes your EXIF data and the
developers don't seem to care. Finally Ubuntu wised up and replaced it with
Shotwell, but unfortunately it is not quite ready for prime time, IMO.

DigiKam has been consistently a great application from day one. Another
great KDE app that many GNOME users should try is K3B (which is a burning
application, KDE Burn Baby Burn is what it is short for). I also prefer
Amarok to Rhythmbox, but that is more arguable since Rhythmbox is very good.
GNOME has nothing good for Usenet, but KDE has Klibido which works great.
Also Evince for GNOME is not nearly as strong as Okular (document viewer).

So GNOME users should not hesitate to colour outside the lines a bit. They
may like the results. The same could be said for KDE users. There are
several good GNOME apps that they should try (Cheese, GIMP, Dia to name a
few). Together GNOME and KDE are formidable. Separately they can be spotty.

Fast Stone Image Resizer runs under Wine, and it works.

I used Xnview under Windows and Ubuntu as well, but now under Ubuntu it is
not good; the pics are transparent.
I made a .deb from an xnview .rpm by using alien. There is still no .deb
package for Linux.

I use Photo Filtre for quick fixes..it runs under wine very nicely..

get a copy at snapfiles.com I like the one click fixes...but it has some more
features than I know what to do with..

I've used xv for that sort of thing since the 90s...............
