I want to have the best possible quality in a zoomed photo in ImageGlass. Should I choose the "high-quality, bicubic" option in zoom optimization in the ImageGlass settings?

You are getting into deep waters here but I will try to keep it simple.
Since your expression 'zoomed photo' is not exactly clear I will take it that you wish to increase the size of an image in terms of the number of pixcels, say change an image from 200 x 200 to 400 x 400. You can use the Bi-cubic process but there are better if they are available to you. In ascending order of efficiency these include Lanczos, S-spline, S-Spline XL and S-Spline Max.
But be warned, you may be disappointed. All size increases work by using one or other algorithm essentially to guess what colours the added pixcels should be. If at all possible you would be much better to re-shoot the image from closer in to get a bigger image and, if possible, work in RAW format and only convert to JPG as a final step.

Hi Chris
I am sorry that my explanation was not complete, because I posted in two forums at the same time, I forgot
now I have edited my question and told the relevant program.

Yes, the "high-quality, bicubic" option in zoom optimization in ImageGlass is the best option for getting the best possible quality in a zoomed photo. Bicubic interpolation is a type of interpolation that is often used for zooming images because it produces smooth, high-quality results.
The other options in zoom optimization are, Nearest-neighbor, Bilinear, or Lanczos. These option produces better quality results than nearest-neighbor, but it is not as good as bicubic.
