Graphical editor

I’m looking for an image editor that can handle “see through”. I want some areas (or pixels) in an image to be see-through so when I put them on a webpage one can see the background through the designated areas. Unfortunately MS-Paint has an option to make this possible only I see the background as white.

Does anyone know such an editor (preferably a free one)?

Try paint .net

By "see through" I believe you mean "transparency". Photoshop is very good, but expensive. Gimp is an open-source/free version of Photoshop. Check out Gimp

Gimp is NOT "an open-source/free version of Photoshop." As it says in homepage:

"GIMP is the GNU Image Manipulation Program. It is a freely distributed piece of software for such tasks as photo retouching, image composition and image authoring. It works on many operating systems, in many languages. (more…) "

I use both Gimp and Paint.Net.

For website design, I also really like Inkscape. Unlike the Gimp and Inkscape is a Vector Graphics Editor, which helps out for some things.

Thanks all, I’m gonna try each one of them.

(@Jonah, yes I meant transparancy, the english word just wouldn’t come to mind <_< )

for fast editing i’m using:

  • web based ‘photoshop’ light edition :) for most cases it’s more than enough :)
