I have been having some trouble fitting my desired image across the full width of my homepage. I cannot increase the pixel, only decrease it and I’m not technical at all, so cannot think of any other ways. I have looked for videos on YouTube and on other forum posts but can’t find anything that can help me?

Are you referring to the image in the slider? The recommended image size for the slider image is 1920 x 760 px. Please upload the recommended image size for it to display full width.
