[Typo3-dev] use IM combine funtion in an extension

[Wengrzik, Andreas]

It looks like it supports subgalleries and random image preview, does it also supports
something like comments, user upload or rating?

Take time for cleaning up it would be better release a good beta than release 
something which will be updated daily IMHO :)

But its really great that the community gets a new actually image gallery!!!

Are there plany for new features?
Umm sorry i dont want to demand so much - it´s just a question im really prying about that extension :)

Have a nice day!


Maybe there should be a new sub-mailing list for an Gallery??
