From Ryebreads photo tips FAQ
*2. The photo must be within the file size of 102,400 bytes. This means to be sure that your file is below 102k in size.
* If you get this message ~ The file that you have tried to attach is too big. The maximum size is 102400 bytes. It means that you still have too large of a file and it must be compressed more to post

Forgot to add this - I dont know if photodeluxe is the same as photoshop in its menus but its really simple to compress an image, just click on Image, Image Size, set resolution (I personally like 640x480) then when you get the choice to save the file, save it as a .jpg image, and a compression screen will appear with a slider that you can adjust the actual file size of the image.
