Make stupidly large emoticon mosaics on http://brawl.com
Once you've downloaded it, you'll want to open a terminal wherever you put the jar. Run the jar in some JRE like so:
java -jar emote.jar <path-to-image>
Where path-to-image is the absolute path to whatever image you want to convert. The program will print the emote "code" to the terminal, so you'll probably want to redirect the output into a file, like so:
java -jar emote.jar /home/phanta/lorem/ipsum.png > emotes.txt
The above snippet will turn the image ipsum.png into emotes and put the in emotes.txt, which will be created (or overwritten) wherever you ran the command from.
WARNING: Try not to use the program with images too large, or it could cause a lot of lag for you when you try to paste the emote "code" into the forums. I suggest sticking to around 48x48 at maximum.
