How to make background invisible after cutting out image

Hi,

I downloaded a 3D book cover and successfully placed the image of my book on the 3D book cover template.

The problem is, the book image now is against a white background.

I wanted to remove the white background, so I use the Magnetic Lasso tool to get the marching ants around the book.

This is probably wrong, but I then chose "Inverse", but to my surprise, at least then I had marching ants not only around the book, but also around the outer perimeter of the white box that I'm trying to remove.

I then chose "Clear" and I got the transparent checkerboard where the white box used to be and I thought I was good, but when I export the .jpg, the white box is back.

Any help would be appreciated.

Thank you.

A jpg can't save transparency. If you need a transparent background, save as png.

A wee tip when aligning rectangles to 3D faces like a parallelogram with perspective. It always pays to make the layer you are Free Transforming a Smart Object. The reason is that if you need to fine tune the alignment, the next time you start the Free Transform process, the box and handles will form a new rectangle perpendicular to the document boundaries.

With a Smart Object, no matter how many times you repeat the Free Transform, the handles will always remain on the original corners. This makes it a lot easier to align the corners and sides to any perspective aids you might have used.

The key words you posted were "........when I export the .jpg, ............."

The jpeg file format does not support transparency. To retain it you will need to use a file format that does - such as export to PNG or save as TIFF or PSD.

Depending on the colour and tonal value of the cover, you might be able to simply use a blend mode. I have added a small stroke so you can see the outline of the picture, which has a white background.
