Actually, the software I recommend and really love using can be used to create almost any kind of graphics you need 
for your website or to sell or to use on clients website. The software in mention is The Logo Creator by Laughingbird Software.

Here are some of the really neat features of this software:

The Logo Creator software is really easy to use and will get you designing stunning graphics for your websites and other projects very quickly. This software app is designed for the absolute newbie so you can be assured that even your grandmother can work this software.
I personally use this software to create web graphics for my many websites. The user interface is really good and intuitive. I use many of their readymade templates that I modify to suit my needs. The results I get are outstanding and the graphics generated looks like they have been created by a professional.
I have never sold any of the graphics I have created with this app yet but I have used them to create products on Zazzle and CafePress and also on TeeSpring. I have also created several banners and company logos for my clients.
My suggestion to you is to get this software now before they raise the price. Stop spending money on graphic designers when you can yourself quickly and easily create better graphics than them with this software app.
