J'ai finalement réglé le problème.
Ce que j'ai trouvé sur un autre forum et appliqué, au cas où ça aide quelqu'un:
Faut modifié une option avec l'écran :
1. open control panel
2. type color in the search bar and click on the green color management link
3. in the dialog that appears tick the box under your monitor name which says "use my settings for this device"
4. click on the add button
5. There will appear a list of color profiles. You want to select sRGBIEC611966-2.1 and click ok
6. click on the set as default profile button and then close button

Ca fonctionne chez moi en tout cas
Taken from the Windows Live Photo Gallery blog:
Q: Why do my photos have an odd color cast in the Photo Gallery (but look fine in the XP Picture and Fax Viewer and IE)?
The photo viewer in Photo Gallery is a color managed environment (it can use a color profile to render a color-accurate representation of your photo). The XP Viewer and IE (and many other applications) are not color managed. Color management can be a complex topic. It's possible that there is an incorrect color profile embedded in the photo, or perhaps you have an incorrect color profile applied to your display device. Following these instructions may fix the problem:
1. Control Panel->Hardware and Sound->Color Management
2. Select your display device
3. Check the box “Use my setting for this device”
4. Click Add
5. Choose “sRGB IEC61966-2.1” (this is the color profile that IE is using)
6. Set it as default.
