Irfanview is an image viewer that resamples beter quality than Photoshop in my opinion and it loads and acts right from the desktop (PC) very quickly... I use it to tweek textures as it is given that it has B/S/V and gamma adjustment. It can batch resample too. I think it just has better sampling algarythms than PS and it is Freeware. My manager always tell me that defraging is unecessary but I do it anyway. Do 1020 maps render fast than 1025 maps? You now what I mean, binary factors sized? Is there a rule of thumb on optimal map sizes?
