I recently finished some massive job on creating 208 door icons and images, so i am still in the mood of doing the same thing for another employer. To be honest, i used Illustrator for that, cause it allows vector images that can be scaled as you like, and it might be wise to do the same here. But, it you insist, Photoshop it is. About the doors, i may need some explanation about the specific parts that i dont understand, i am not door expert after all, but i dont expect to have too many questions. The most important thing is, do you have psd files of currently used images on the website, it might short the time needed to create new images. What is he size and resolution you want, and since there are some painted glass parts, do you provide them or should i do them? Since you also need double and triple part doors, do you use some t-astragals to cover them, and do you want them all in white? Shoud the panel configuration and glass frame be the same, kind of raised, or you plan something else? Hope to hear details.....
