Recently, I find that error message "Invalid image file." pop up when uploading photo.
Several PCs are tested. Finally, I think it is caused by the upgrade of the browser, Internet Explorer, from version 7 to 8. The uploading is successfully when I install and use another browser - Mozilla Firefox.
Can the administrator do something at the server side to fix this issue?
I think there will be increasing number of persons will upgrade their browser and not everyone has another browser installed.
