Thanks, eskro, one week ago I saw your anser, so I decided to give a try to zoom fileuploader (v4 and v5).
Meanwhile this piece of software was superb to upload files to several servers (actually I use DepositUploader, RapidUploader and so on), the results wasn't very good for me compared with Rightload.
The nightmare behavior was: with Rightload, I only do a right click on the image, send to any server (ie, imageshack), and there you go: I got instantly in my clipboard the url with the image in imageshack.
With zoom, is really a pain. I have to wait to a stupid-annoying "welcome screen", press OK, then opens a window with too many file servers, I have to do click in "image servers", select imageshack, then click OK, and shows several links to choose the image.
If you know something easier to only do a right click in the image and send directly to a image server (or file server) without more clicks and time waiting, I'll glad to hear it. If not, I recommend to stick with RightLoad. Hope soon we get a 2.0+ version.
Thanks anyway.
