You should now be able to work out the figures for the other pictures yourself. Remember, they are 128x128 blocks. The first two numbers are the co-ordinates of the top left corner, the last two numbers are the co-ordinates of the bottom right corner and should each be 128 more than the first pair. Given the co-ordinates of one picture, the next one along has the first and third numbers increased by 128 - unless you're onto another row, in which case the first number is 0, the third number is 128, and the second and fourth numbers are increased by 128 to go down a row.
So, if the co-ordinates for the salt are 512,512 and 640,640, what will be the co-ordinates for the next one along?
Paprika is 0,256 and128,384. Subtract 128 from the 2nd and 4th numbers to go up a row, which means whatever is above paprika is at 0,128 and 128,256. Now look in "pictures.ini" to see which good has those co-ordinates.
