I'm pretty sure TheBlasphemer said that oversized emoticons are not possible in WLM and therefore wouldn't be in Stuffplug 3. It had something to do with the fact that, even if you sent an oversized emoticon to your contact (who has WLM), his client would resize the picture and you couldn't do anything about it. The good news is, you can have emoticons up to 50 x 50 pixels instead of the usual 19 x 19 pixels, as long as the emoticon is animated (for still ones, you can make an animation of a the same picture twice
).
