HUGE news!!! ( mopar muscle magazine )

I kind of missed the part where you say you upsized them by increasing the pixels. What size were the originals? Upsizing alone wil not increase the resolution they need as it usually reduces the detail. If you need to, you might need to reshoot your pics.

Figure it like this - you need 300 pixels per inch at "print" size to give them 150 line screen. That is without any resizing/modification :)
