Effect Files
Follow this link to view the graphics used by the actual effect files. They can be also be found within the Effect directory in an extracted iso or in Shishi Sprite Editor's more recent versions, in the Other images tab.
A thorough reading of this topic will provide information on editing these: http://ffhacktics.com/smf/index.php?topic=116&postdays=0&postorder=asc&start=260
By converting the hexadecimal value assigned to the effect in the FFTPatcher's ability tab you can pinpoint which effect file is which within the directory.
A video compilation of all effects can be found here: http://ffhacktics.com/smf/index.php?topic=4830.0
There is a bunch of translated information about effect files in this thread: http://ffhacktics.com/smf/index.php?topic=6979.0

Pickle Girl Fanboy here. All of the above image links are dead. I recommend someone resubmit images to an image hosting service which will hold images indefinitely. I recommend the following service: http://www.myupload.dk/
http://www.myupload.dk/faq/ ^Their FAQ says, "There is no time limit or life time of an uploaded file. However, we do recommend that you sign up for a private upload folder to keep track of your uploads."
Again, this is NOT a bot. It's me, PGF. The two links above are valid. PGF 23:51, 15 February 2012 (CET)
