It is probably a digital image printed by inkjet. As such, it might be damaged by application of heat, moisture, or pressure. Or maybe not. Infinite substrate/inkset/printer variations in the marketplace now, and there's no way to determine their limitations in advance, unless you know the details of their creation. You feel lucky?
Stretching is usually safe, but be careful about abrasions and marks on the image surface, which could be very fragile. Also be careful not to stretch too tightly, as the ink layers could crack at the edges. Also be careful not to stretch too loosely, as the canvas may relax and sag in a short time.
My favorite method is to use Lascaux 360 contact cement and a good quality board, such as 4-ply or 8-ply alphacellulose, reinforced by Coroplast. Chemical content and stability is important in framing digital images, so do not use just any contact cement.
Apply the contact cement to both surfaces, let it dry to the tacky stage, then join under moderate weight. If you have a vacuum press it might work perfectly, unless the extreme pressure and/or vibration of the machine would abrade the surface. Padding in the vacuum press doesn't seem to help if the image surface is fragile.
Digital images on canvas are among the most troublesome things we have to frame these days, because they are so unpredictable. Good luck.
