A few days ago, KlausST posted an instructive comment and an accompanying link in a thread, the post was about image size and contained a link to an online tool to do so. Does anyone remember the thread? Thanks.
Not finding it now has made me think that maybe, if there's space, putting the link to the re-sizing tool at the top of each forum section could be helpful?

I can´t say whether this is a good tool or not.
There just was a member looking for an excuse .. and told he has no tool for photo editing.
Thus I did an internet search .. and this was one of the first hits.
