I have two items in my signature. A sentence and a banner. Several times now, after posting I noticed that the banner in my signature does not show. A few minutes later it may show again. Why is this happening ?

Well, you're banner is coming from the website, meaning that it is reliant on the sites server to have the image show here. If there are any connection problems with MMG and the other website server, it probably won't show.

There are a couple different reasons why this might happen. Just something that happens occasionally.

The server where you image is hosted may be having issues.

Thanks for your help. That makes sense. I went back here to check for an answer because my banner had disappeared again. At the same time I see the same banner on other member's posts, but I guess because they posted at a different time it still makes sense.
