Actually, you don't need to convert to bik first.

In RAD Tools, browse to the location of your image files. If they're numbered sequentially (img_0001-360, etc), select the first image and click the 'List Files' button. You'll get a popup asking if you want to treat the sequence as a single animation, click yes. A list editor will pop up, check to make sure the list is in the correct order (an auto generated sequential list will look like 'img_????.ext*1-360'), save the list in the same folder as your image files (the lst file will appear in RAD Tools browse window).

Select the lst file, click the 'Convert a file' button. The converter has a ton of options. If you just want to make a simple avi, all you need to do is tell it the frame rate you want (in the 'Force (no adding or removing) to:' box), select the output type, give it a name and click the convert button. Another popup will appear allowing you to choose from among the codecs that are installed on your machine. Select the one you want, click ok.

However, my personal suggestion would be to use virtualdub, wolf359 as mentioned above. It's very powerful and not TOO hard on newbies.
