Wrong images display

I had a bad experience last night trying to re-arrange my webpage. I moved some text and images around and then uploaded the files. The wrong images displayed in the wrong places. One picture displayed in the place a different one was supposed to. It was strange. I’ve had this happen before, too. Does any one have any idea why this happens or what to do about it? It was a pain getting everything right.

You haven’t given enough here for anyone to be able to help you.

Is your site built on a CMS (like wordpress), or generated with a page editor (like dreamweaver) or how was it created?
