I voted tuxpaint because i gave it to my nephew (3 years) and it loved it

Imagemagick.

How else are you going to type on the command line: "convert this.thistype to this.thattype" and have it happen?

you left out
ISIS 3 from the U.S.G.S.
and Nip2/vips

Imagemagick but...
 

Agreed !!

I have overused imagemagick so much this days that I couldn't vote for my beloved Gimp and Inkscape. Two finest applications which are doing a lot of improvements.

One should recognize also the Xara's people efforts. I'll test it again right now.

yeahr, there is a reason why they are called "BIG" in short :D
hard choice...

FPDF
 

I'm using the heck out that right now. Maybe purists don't consider PDFs graphics. If not, then what category should this be in?

there's only one, and it is not (yet) for linux, and you all know which I mean, Yes it's Photshop!

Mostly I use Gimp...maybe am lagging in this area (self-motivation!).

Useless poll....
GIMP owns all the way.

Well I guess I'm going to have to vote Blender as it has become my new favorite toy, I still use gimp for painting my models though :P

Graphics app of the year
 

A lot to choose from here. I like Inkscape and Gimp, but for all around usefulness and features (even though it's nowhere near complete) I'll have to vote for Xara. I use this a lot at work and it's the closest thing to CorelDraw I have found.

I've shifted my vote this year to Krita.
 

I have long been loyal to gimp, but krita's UI design is just better.

I hope it is a wakeup call to the gimp team, UI design matters. Indeed I hope krita and gimp merge again.

I voted for tuxpaint. It's a fun challenge to try to create serious artwork with it, easy to use, and I really like it. I do use Gimp a lot too, but I've got my locale set to Macedonian, which is good for learning the language, but bad for using complicated programs like Gimp at this stage of learning. ;)

Man, I was so excited when I found out about Inkscape. GIMP is old news and kind of blows anyway, my vote is definitely for Inkscape. It's one of those projects that measurably improves the quality of a GNU/Linux workstation.

With a Non-linear video-editor, audio-editor, game-engine and 3D Modeling app/Texturer/Renderer/UV/Physics simulator all rolled into a single production power-house super-burrito package, I have to go with Blender.
