Yes, Ok I had read this web page. Now I used this code "+SR0.44 +ER0.61
+SC0.58 +EC0.75". The main picture is in 1280x960.
1280/25= 51'2 and 960/25= 38'4.
How can I now if my square is 51'2 width and 38'4 height? Because I supose
that if the square is biger than 51'1x38'4 I can't upload it.

"In the above example, detail #1 occupies the area 424,328 to 615,583 in the
960x1280 image. This equates to +SC0.441667, +EC0.640625, +SR0.25625 and
+ER0.455469. These values are simply arrived at by dividing the desired
column by the width (e.g. 424/960) or the row by the height (e.g. 328/1280).
These won't necessarily always equate to the exact pixel you want but it
will be close enough for the purposes of the submission."
424/960= 0.441667, so +SC0.441667.
328/1280= 0.25625, so +SR0.25625.
How do you know the other number that appear on the exemple? ( +EC0.640625
and +ER0.455469).

I suposse the coordinates are my code: 0.44, 0.61, 0.58, 0.75. Is it?

Thanks to all the people who are helpping me.

Best regards,
Oleguer
