The iGUIDE Portal and many browsers ignore auxiliary image information stored in EXIF headers and embedded color profiles. Common problems in such cases include images rotated 90 degrees (rotation information was stored in EXIF header) and wrong coloration of images (color profile, sometimes incompatible with monitors such as printer CMYK, was embedded into image). To avoid these problems, do not embed color profiles into images, export them with sRGB color profile, strip EXIF headers and verify image orientation without the EXIF headers.
