In response to feature request: "Extend image info - ID: 3014344", here's a quick stab at displaying the image size on the "List All Images" screen. It reads the file sizes on the fly via ls -lh and uses awk to pull out the relevant part. It seems to handle multiple partitions OK but I've not fully tested this - certainly it shows our test W7 image with 2 sizes.
No sorting has been put in place for this column - feel free to add this in if you feel you need it.
Location for the amended file is /wwwdir/fog/management/includes
I'll look at the date field later if I get time, I agree with the feature request that the time/date the image was sritten would be more useful than the time the image placeholder was created on FOG.
