Issue with imagej, reading jpeg files

Hi everyone,

I´m triying to upload image to run the pluggin IJ RHIZO, when upload the file is appearing this warning message:

Error: loading image
(Note: IJ can not open CMYK JPEGs)

Could you help me? my images are in JPEG format

ImageJ uses Java to open JPEG images and it cannot open some types of JPEGs, for example those that use the CMYK color space. The work around is to use another application to convert to TIFF or PNG.
