When I add an image/gif to my signature it works perfectly. However, after a few hours, the image is no longer visible! I tried going back to my settings and putting the image BACK in the siggy, and it works... but it continues to dissapear.

Help???

Next time when the imahe disappears, please try checking the availability of the image server where you host your signature image. Many of the image hostings are unstable, and images may become unavailable from time to time depending on the hosting.

If the signature disappears completely (meaning the whole signature code and not just image availability), then please make sure that nobody else has access to your account.
