Artists who build graphics for the web are growing in ranks every month. New and upcoming designers are always thirsty for more knowledge and insight towards building layouts. Adobe Photoshop may not be the perfect software, but it does provide all the core tools you will need for mocking up a website interface.
I have put together a series of 32 Photoshop tutorials which relate to building lots of different website graphics. These tutorials also focus on mobile interfaces, icons, logos, badges, banners, and other typical page elements. I think it is important for designers to stay on top of these creative trends. This way your new projects will always be cutting-edge in comparison with other websites within the industry.
