imgmirc v0.29beta (which should work with mIRC 7.0 and mIRC 7.1) can be grabbed here:

A few words about \'.idata section\' error: this would appear if you use imgmirc of version first posted here with mIRC compiled with VC 7 compiler. I don\'t know about another sources of such an error... In general, this error means, that mIRC.exe is \"strange\" and imgmirc can\'t find the place in the executable where to hook its functions. So, if you managed to run imgmirc somehow and it works, just let it slide.
Animated smileys are something not very easy to implement because of the way imgmirc works. I don\'t know if there will be the next release, but if it will, i\'ll think about animated smileys. Regarding smileys in editbox: again, there is no possibility to add smileys there in similar to other windows way. But, there is even easier method to do that in editbox, because it is RichEdit now (though it still requires some coding).
