If I attach photos to a painted canvas and use a acrylic varnish on the whole painting will it ruin the photos?

I simply want to know if i can put varnish over photos attached to a painted canvas and if i cant what can I use to make it seem like the photos were not simply stuck on?If I attach photos to a painted canvas and use a acrylic varnish on the whole painting will it ruin the photos?
I would use matte gel to embed the photos in the background, it dries clear and covers everything (plastic coat;, but if the photographs are inkjet prints, they will probably smudge.


A better choice would be photo transfer: coat an injet print of your photo with 4-5 generous coats of matte gel; wait for it to dry; moisten the paper on the back of the print and gently rub the paper off; the image will be transferred into the clear hardened gel and the white paper will rub off. Your image will keep its properties and its now sitting on a clear support. Apply it to your desired support and coat-seal with gel again.If I attach photos to a painted canvas and use a acrylic varnish on the whole painting will it ruin the photos?
Real photo's will do just fine. If you use bubble jet prints you may smear them. Prevent this by giving them a spay clear coat before sticking them to the canvas.





On the second part of the question:


No matter what you use the photo's will apear to be stuck to the canvas.


Let me explain. When you stick paper to a canvas there will be a little 'shrinkage'. Paper just does that and canvas, no matter how taught will show that.
It depends on how the photos were printed. If they were printed on photo paper by an inkjet printer, the ink might run when it gets wet. If they are actual photo prints from a photo lab, they might be OK. Either way I think you're going to have the best luck with a sealant you can spray on rather than paint on.
you can use spray mount
