Apologies for the capitals, but needing help, fast. I have been chosen as one of the three winners in the RPS monthly competition. They require a high res version of my image by 9.00am tomorrow morning to make the print deadline for next months Journal. They have requested a 40cm x 40cm image. It is a tad over 27cm's square in it's native form as a TIFF. So I resized it to 40cm's and saved it as a jpeg, but it comes out at 26Mb which my e mail account won't send as it's too large. Is there a work around to get the file size down, without losing the dimensions?
