I would like to download code for image viewers such as sliders, carousels, galleries, magnify and zoom.

I have searched online and I feel like I am drowning with no way out.

I guess it's better they are responsive, compatible with older browsers. I get the impression Jquery ones are faster and smoother.

My questions are:

What image viewers do you recommend for sliders, carousels, galleries, magnify(image pops up larger) and zoom (lens moves around image showing a close up of that bit)?

Where is a good place to download code? e.g I found code canyon, but then I drowned again. I feel that someone with experience with many image viewers would give better advice than I have found online. A real person )

Thanks for your help.
