Cartoon Smart 出品的使用确Flash 上传文件的教程，时长4个小时。

教程主要内容是如何使用 Flash 上传一个文件，然后在 Flash player 里显示画面。

在第1部分中，将学习如何在 Flash 界面下简单的上传一个文件 (即浏览你的电脑图像文件，并上传到服务器)，然后图像将在 Flash 界面里显示出来。文件不一定非得是图像文件，但是如果文件不是 PNG、 GIF 或者 JPG 格式的话，你就不能往下继续做那些酷炫的效果了。

第2部分和第3部分的课程内容是这些类型的4个应用例子讲解。

This video tutorial teaches how to Upload a file using Flash, then show that image in the Flash player. The course summary is below…

Part 1 of the tutorial teaches how to simply upload a file from a Flash interface (that is, browse your computer for an image file and upload to the server) and then that image gets displayed in Flash. The file doesn’t necessary need to be an image file, but if its not a PNG, GIF or JPG then you can’t do all the cool stuff to follow.

So Part 2 and 3 of the lesson cover the follow scenarios for what you MIGHT want to do with this application….

Scenario #1: Upload an image into Flash, and then the image becomes drag-n-droppable AND dressup-able. So the library can hold different items you might want to dress up the image with. The example file just uses a hat, but you can extend this to
tons of different images. And once you dress up the image, the user can print out the final composition.

Scenario #2: Upload an image into Flash and a looping motion tween is applied. So the image kind of hovers. Again you can drag and drop the image, but this time a bullseye target appears and if you drag the image over top, a hittestObject command will call a function to do whatever. In the example file the image kind of shrinks and "sticks" to the bullseye, and calls a URL to open.

Scenario #3: Upload an image into Flash and set a mask for it. So both the mask and image are moveable for fine-tuning, and you can then set / unset a mask for it. The mask can be any shaped-design.

Scenario #4. This time the user can upload two images from Flash which get used in an animation ( jibjab.com has the best examples of these animation ) And instead of using preset masks like the previous example, you can adjust handles (or control points) on the mask to get a better masking effect. And of course one image could be a head, the other could be a mouth, and then you can animate those however. The end example basically leaves you with everything you need to start keyframing a lengthy lipsynced animation. But keep in mind, the jibjab reference is just one possible thing you could do. You could just simply create a canned animation using someone’s logo or whatever. Fade in, fade out, whatever.
