You can go to their website and find what all files they will accept.....and they accept a lot!!! I uploaded mine in .psd format. I have used .tiff and .eps as well. I was told by my last designer that .psd offered the truest colors. Personally, I have no idea of any truth to this....just going by what he said. 13 days is about what I expected. I was thinking between 2-3 weeks...so that was good. Make sure you view the proof and accept it (if it's correct) as soon as they send it, that will speed up the process. Do you have any pics of your doorhangers?
