to bend a whole image in corel (i use cdr12) you need to use the envelope tool, just beneath the text tool (A), click on it and it opens to the right, envelope is in there,
i would use a copy of the file to play with, always keeping an original until you get the curve you want, there are various settings n the top task bars, which enable you to play around with it in different ways, ie, curved bends, angular, etc. it’s not the easiest of tasks, and always takes some trial and error to get right !
