The easiest way is to open a free Photobucket.com account. Upload you pictures there. You do not need to re-size them.
Copy the html line beneath each photo and paste here in the message portion of the post. You can paste multiple pictures within the message.

There's quite a number of FAQ's on how to post photos to gardenweb. See link.

Thank you very much, carol 123 and fatamorgana. I will work on your suggestions. As I am not computer smart at all, it may take me a while to learn the way to post good pictures. Thanks again Hazel

I hope this will help. Here's a picture from my Photobucket album. I've highlighted, then copied the HTML line. I then paste it here in the message area along with any text.

It's very kind of you, carol123. I've got it! It was very easy even for me. (I tested it on the preview and it worked beautifully.) Now I also know how to e-mail large photos to friends. Thanks again Hazel
