yes alright, but batch process can only batch one folder and no subfolders. so aou would have to do that for every user folder, right? quite tiresome...

bump:
has development on gallery plugin stopped? could someone maybe take over the development or help nant out.. seems he is quite busy..
there are loads of feature requests and suggestions for improvements... and no advances it seems

You may find your solution in ImageMagick there is a command mogrify that will batch resize images. You must install ImageMagick on your server and have root access.

Allow me to follow up here.

You will need root access to the server to pull this off. Also you will need ImageMagick installed.

Process:
Get all of your full size images. (I did it like this:)
[code:1]
cd images/comprofiler/
mkdir ./thumbs
//get all the images
cp ./* ./thumbs
cd thumbs
// remove the non full size images
rm ./tn*

//use image magick to resize (use your own dimentions)
mogrify -resize 80x80 ./*
[/code:1]

Ok, good. Now download a program called ant renamer. Also use FTP to download the thumbs folder. Use ant renamer to rename the files; Use the "regular expression" option. replace ^ with tn. That should put a tn in front of all of your files. Now upload the renamed files to images/comprofiler/

Hope this helps... I'm not sure what plugins you guys are using.

Fixed below... Stupid code blocks
