I have designed an image to be used on our companies show stand ...the image is very large at 116 inches x 91.5 inches.
It's taken a while but i'm finally there
I have tried exporting to a jpeg now twice so i can upload it to the suppliers site for printing but it keeps crashing Corel!
Any idea as to what i can do?
