When I resize these icon size images for the front category page they look very pixelated (especially on mobile) as the required size is a very low 48x 48. How can I add code to the source hrml or css to allow larger resolution files to be used but then resized to stay the same size on the page?
There actually is no required size for the forum image. In the attached screenshot, I've just tested this for example using a 600x800 image as the forum image.

Although its recommended to maintain a standard width and height for each forum's image you use, its not required. The stock sample images are 48x48, but can actually be any dimension. Their container will adapt to the size of its image.
NOTE: when you create your 48x48 or 100x300 (or whatever you've chosen) image, save it without compression. The blur that you are seeing without zoom, is caused by your graphics program setting to compress the image upon saving it. Obviously, if you use your browser's zoom in/out on any page, you will be increasing the size of each pixel on that page, and they will become more apparent.
I'm looking for the css sheet below but its not showing up in my hosting file manager. screens attached.
It is located within the /styles directory.
common.css helps browsers render all elements more consistently and in line with modern standards. It precisely targets only the styles that need normalizing. It is a common CSS normalize/reset for UBB.threads. Not something that you'd want to edit with anything specific, since its intended to hold common layout formatting, and attempt to render your forums the same across all web browsers.
