heres a link to the two actions i use to sharpen my pics. the first one is what i do as soon as i open the pic in PS then do curves then save and thats usually it. after i'm done editing i'll use the second action in this set on that edited full size pic that sharpens, resizes the pic to 900px on the long side, saves the resized pic to a resized folder on my desktop then closes the image. if you download these and use the export resize one then while you have an image open expand the second action and double click "save" so that you can edit which folder you want your resized images saved to. if you dont want it to do that, just delete the "save" and the "close" steps at the end of the action and it will do everything but them. let me know if you guys like it or if it helps your web image sharpness
