Qole, quick question: is there any way to chose what size the img.ext2 for Debian is?

I had tried to resize it with resize2fs. The image actually enlarged to 1.7 GB. but Debian wouldn't recognize it and I ended up reinstalling it from scratch (which didn't take much time at all.) So, aside from setting the size initially, can I safely change it now?

Thanks a lot for any help and for this great system you've got going, I love it
