You do know if you use Signs IV and turn that photo into let's say a picture that is to be hung on the wall... Signs IV gives you the option to add a script to it.... So like if you want to add health to the character or just give the guy a simple message when he walks up to the picture on the wall you can do this with that program.
Signs can be gotten from here

As far as windows and doors unless your using what comes with FPSC your not going to really find anything on the forum, Now model pack 3 has your best selection of doors and windows and model pack 2 has a few doors (bathroom doors) to choose from
or you can try what JohannesM has suggested by retexturing...Since your new to the forums I will try to give a few hints to help you...
When working with a model say for instance a door look in your segment folder first for the .fps file open it in your notepad....look at it...the door will actually point to a fpe file (entity file) that file can also be opened in your notepad
Probably asking why do you look there....simply because those 2 files have all the information where your model is, where the texture is, what scripts are being used with that model so with those 2 scripts you can locate your texture and be able to work on that, change the aspects on how your door works like wether its automaticly opens or needs a key to open etc
note: not all models use 2 scripts, but doors and windows do
