How to put a picture on imported picture frame within my model

I want to put a picture on picture frame model. it has material that i want to put a picture in it. using materials setting to create a texture is difficult to make picture fit into position correctly.

Hi ijagga
Please use the Material Picker to select the picture you want to change and under Base Color Map (on the right) you will find the picture that you want to change. Click it, then the system will open your files where you can select the picture you want to put in.
Maybe, if necessary, you need to use UV to scale the size.

Yes. a little difficult, it is.
therefore would be easier in the CAD program.

Yes I do that, but sometimes it becomes tedious to make picture balance fit. Maybe if there was option to fit only one surface image without repetition. that could work more easily for us.
