How come some pictues load up instantly and others just say "IPB Image" where the picture is supposed to be?

There are a number of reasons where the photo is:

• a link to a site which your client is having difficulting connecting to
• a link to a site which may have removed the photo
• a link to a site which is offline
• a link to a site which found a photo taking up too much bandwidth and stopped hot-linking

It is always best to attach photos and use ADD TO POST so the photo is stored here. Of course copywritten images are illegal and if found will have to be removed from this server.

I don't understand all of it, but I reckon I understand a good deal of it.
