I need help on uploading games. Please bring some help!

If you know how to upload a game, I would like your help. I'm new to game uploading & I have games I would like to post on to this site. Please Help!

Lets say I wanted to upload a game called "N", I should download the game, upload the file from where it came from, & do the rest, right? I tried before it didn't work. Don't know what "N" is? Go here.

I was thinking about N v.1.4

By swf file you mean software-files, right?

Only the flash file upload step and the game icon step cause problems for me.

I think I had a problem with the flash file 'cause it was the wrong file. The image size is 13.8 KB., 65x72 & its a bitmap image.
