NateL, it didn't work...

I have written your init config in the top of the function that uploads the image; the image to upload has 807kb, and I get thids error:

Fatal error: Allowed memory size of 12582912 bytes exhausted (tried to allocate 2576 bytes) in /hsphere/local/home/sergiopo/sergioporto.com.br/admin/system/libraries/Image_lib.php on line 1157

D'you know how I could solv this problem?
