1) i'm sorry for any problem, but the software running this forum is not made by me. But it's open source, with a big community, and new better versions are released from time to time. The picture problem was probably due to some sort of bad caching.
2) I know of no ICQ group (and i can only guess the meaning of that). Maybe there was some mistake about the fact in the past i worked on another project: an ICQ compatible-alternative.
3) as foggy said. and i can't do nothing about it, because it's a limit of HTTP itself. Even i i would, the browser would not, resulting in nothing useful.
4) yes, but only in the way You(HFS) ===> Friend (that is, download)
If it does not, it means your friend is using a poor software for downloading.
