This forum supports the ability to attach one single photograph. Above the message box where you create your message, you'll see the text Image file to upload (optional): and a browse button to choose the picture from your PC or device.

Once you've attached your picture, preview your message and then select "submit".

If you need to attach another picture, you will need to create a new entry (it can be in the same message thread). If you want to practice, find the "Test" forum in the list of all forums.

You can also provide pictures by using a photohosting site like Photobucket, Flikr, Picasa, ImageShack, Webshots, Shutterfly, SmugMug, Snapfish, etc. These sites usually let you create a free account and upload full sized pictures.

Once your photo (or photos) is uploaded, you will be given a link to share your pictures with others. Copy that link and paste it in the body of your message. You can have multiple links if you have multiple pictures.

What kinds of pictures should you provide (if you can)?

One of a leaf, close up
One of the stem, where the leaf joins the stem
One of a flower or fruit (or both)
One of the bark if it is a tree or shrub
One of the overall habit of the plant if possible

And be sure to describe some of those things that don't come across in a photo: is the leaf rough or smooth, does it smell like anything in particular, do the flowers smell, does it grow fast, where did you get it from, see it or find it? Sure a picture is worth a 1000 words, but we need some of the other words too!
