depends on the situation... if you've taken a portrait of someone and they look good (maybe better than real life) and someone describes it as 'glamourous' then I'd think that was a good thing, you've probably captured a bit of them in the pic and people are seeing that.

A 'glamour' feature in a photo mag means something entirely different... usually scanitly clad women in inappopiate situations... generally not good (although I'm sure to have a look to make sure!)
