The right click & copy xxx location is a basic way of finding out the actual address of an image, file or other site. Individual computers/hosts may also have some helper utilities/functions/buttons to assist you with that.
You can also use that drop down list to display the underlying image, which may be bigger or higher quality than what is available otherwise. Handy trick to get a better view of many things like eBay images, etc.
As to why you can't just drag/drop/load files on your computer's desktop to this forum: That would require the forum/site owner to install/maintain additional complex code and pay a great deal more to store/manage all the server space needed to store those images/files. The sites that usually allow you to do that charge you to offset that cost. If they don't charge you directly as cost of software or subscription they are doing a google/amazon/Microsoft/apple sort of thing using/selling your info for profit indirectly &/or having businesses pay for advertising/sponsorship.
Dave, who owns/runs this site provides our "free" use of it paid by donations and some advertising/sponsor revenue. he does that without collecting/selling your personal info.
