funny, the idea looks like the program for the GP series of Geoff Cramond: GPXPatch (http://www.xs4all.nl/~rsdi/gpxpatch.html) where all kind of Formula 1 overlays appeared in the game which orginally didn't show up because of license problems.
First: basic black shirt, large logo. Nice for summer and under a jacket.
Second: very simple, also my dad can wear one.
Third: going wild, only wearing this a LAN party and on LfS club days.
I like well suited shirts like they sell at Threadless.
Are you considering "iDeal" for Dutch customers? Since this is introduced I only buy items from webshops which use iDeal. I also looked in implementation and it's very easy and fast.
I worked at a webshop, the same concept you are starting. You can contact me if you have any questions.
If you have a 20.1" it's probably 1680x1050 as said before. My XP just detected this resolution and in LfS it also appeared so I can play at this resolution. If you want to play in 1280x1024 don't forget to change the setting in your videocard so the image won't stretch (depends on videocard).
no, just try and practice... you can't learn using a program in a few hours.
I learnt Photoshop over years and still dicovering new features! Just start using a simple program like Paint.NET, Paintshop Pro and then continue to Gimp or Photoshop. Not to mention: start drawing a sketch on a piece of paper... really helps if it's hard to handle a program like Photoshop.
