You and I both. There was a time I was going to change my name to ThreadKiller.

take a picture
place guides at 32%, 34%, 68%, and 66% (I think. it did take a little trial and error there)
place guides proportionally so that each bit is a multiple of 235x 175
resize so that the images are 175 px high
crop out three bits that are each 235 px (this should be outlined by the guides)
upload 1, 2, 3

what thread did you kill?

been there, done that. Don't feel bad.
