I've been using Photoshop since version 4. I'm mainly doing front end programming and I'm using Phtotoshop for slicing Web design and for other manipulations that can be useful when doing my work.
Photoshop is the only commercial application that I use. Otherwise, I can manage easily with Open Source apps. Is there anyone here that is using GIMP for design / slicing? Any resources you can point me to that could help me pass from the expensive Photoshop to the free GIMP?
The GIMP is a fine editor for a lot of types of work (including web). Depending on your skill level, you may or may not be very comfortable with it, especially if you spend a lot of time in Photoshop (or other tool).
I use gimp for web design, I think its a great tool. I have used both Photoshop and Gimp, and I have found if you are not able to afford Photoshop, Gimp is a great substitute, I know their are several professional web designers that use Gimp for web design, some use both Gimp and Photoshop together. as for learning more about gimp, their are a lot of video tutorials on youtube for learning gimp. Hope this helps (:
I know this is not exactly what you're asking, but have you taken a look at Adobe Fireworks? It is not open source, but costs a fraction of what Photoshop does, and I find it a much better tool for web design.
