This is a great hack, I've installed it on my test forum and it runs fine. However, I have one question/problem:

I'd like for guests to be able to actually see the thumbnails in the gallery-forums (instead of the "you need to register" pic), though not being able to click and see the full size images.

Is this currently possible (using permissions)? or would I need to change some code? If the latter, I'd like to suggest it as a feature.

I'm sorry if thsi has already been answered, in that case I have missed it in this rather long thread :)

Just an update: I have been experimenting with all possible forum permissions, but nomatter what I do it seems that guests cannot see the thumbnails on the forumdisplay pages. (I'm on 3.5.4 btw).

Please, does anyone have any idea what could be wrong? Everything else works like it's supposed to AFAICT. (though I had to manually edit the phrases, but that's no biggie). I'm of course using the latest install downloaded form here.

@Magle:

The next update (coming next week) will have this possibility, you were asiking for. Just look at my new site here: http://www.sf-galerie.de

I guess this works the way you are supposing it to do, right?

That's great news! And exactly what I was looking for - that way the thumbnails can work as a "teaser" inciting people to register on the forums.

Thanks for giving us this mod, Harald_T!

Is this forum what It will look like:

@Larrysw: No, that's not my gallery. This is the tutorial-section build up with vbgeek.

Or do you need an option to have the gallery look similiar like this?

I would use that!

When is he next update? This is a very kool mod I like it :)

I have Coppermine, it's possible to migrate at this gallery?

@tuanluu: I've started working on the next update and also thinking of new feature for this hack.

@mosss: Atm there is no possibility for this.
