Yes, I was wondering the same. When I did the post I saw that the GMail's preview didn't open the image. I already did convert them to work with Tesseract but the original file has 353kb and converting them the output is like twice bigger. I need the same or almost the same file size of these original ones, I tried to convert to JPEG or Tif again and compress these images in VB.Net but to get the same file size I lost a lot of quality.
Anyway, thanks for your answer, this problem has not to do with Tesseract. I will try to find a way to convert/compress without loose too much quality. Edson.
