You can't "post" a picture here on eHam by uploading it; you have to upload it to another web site and then create a link to it here on your post. Maybe we can help you with that.
I know that eHam allowing pictures is new and I am thankful because it really has improved the forum experience but they are going to learn a lesson that so many other forums have learned and that is that they should host the pictures themselves. Some really good threads like this one will be useless in a few years or even months when all the picture links are dead.
If eHam says that it's too expensive for the extra bandwidth and storage then they need to start thinking more long term because forums with tons of dead links is not a good recipe for future success
