Sorry I missed this post earlier. I've had a lot going on the last two days and it's been about all I can do to answer questions and try to get the bugs that have appeared so far fixed.
There is a problem where anything besides jpg and png images are appearing as a red x rather than the default thumbnail that is supposed to appear when an image can't be resized. For right now, if you choose the option to rubuild your thumbnails under the Maintenance section of your vBa Gallery options then that should replace the red x's with the default image. If everyone can hang tight until tomorrow then I should be able to release RC2 which will correct this problem and all other bugs that have been reported so far.

nyifan - Please be sure that your 'ImageMagick or NetPBM Path' option is set something like this:
/usr/bin/ (with the trailing slash there)

The lack of the trailing slash at the end seems to be the cause 90% of the time when ImageMagick isn't working properly. If that doesn't help and you'd like to submit a support ticket I'll be glad to have a look and see what the problem is.
