FWIW, the post you deleted has two attached pictures which are still there (I think these are just thumbnails because I don't see full images in the gallery)
Don't know about file size limits, but will check later.
I'd be willing to bet they were too big however.I think you first need to upload all your pictures, either one at a time or as a group. Then after uploading there should be a button to attach individual or multiple images. I'd just try again with files that are smaller and see what happens.
As for the picture... It was taken on June 16,2002 - wow, where did the last 20 years go?? Let's see how long it takes for somebody else to identify that. Should be an easy one.
