I could only imagine it getting noticeably slower with thousands of images, you should be fine :P. The slowness is just caused by the fact that it has to wait for the page to load and then load one image, I don't think there's any way to make it much faster than that.

Anyway, yep, that's it, as long as you have the images uploaded and get the links in properly. All you have to modify is the list of image URLs once you copy the code.
