Hi,

the problem is the color-profile in the hotspot image.

Browsers with color-profile support will use it to change the colors of the image.

The krpano-tools (and some other browsers and also the Flashplayer) don't have color-profile support and will ignore any embedded color profiles.

Therefore the differences between the pano image (processed by the krpano-tools) and the hotspot-image.

That means try to convert your images to sRGB before using krpano (images without embedded color profile are handled as sRGB images).

E.g. as test you can run your hotspot image through the krpano tools - e.g. this way:

then the image will be loaded and saved again as jpeg by krpano, but this way with ignored/skipped color-profile. Now the hotspot and the pano would look the same because both are color-profile-less.

Best regards,
Klaus
