Now, I was hoping someone with an iPhone would jump in ...
I use my android phone to post pictures. Because TEG has such an easy
save process, I can upload and save an image. Then, I can come back later and type a message on a keyboard that better fits my digitS'

You may need a certain number of posts to use "Upload a File." Do you see that button beneath the text box?
You can click that and find the picture in your phone by clicking "Documents." Clicking that picture results in TEG beginning to upload.
You see the image uploading below the text box and will then be given the choice of "Thumbnail," "Full Image" or "Delete."
Set things up in your text so that your picture shows just where you want it and click thumbnail or full and the picture will appear right there in the post after you click "Post Reply."
As I say, TEG may have a minimum number of posts required
before you can upload a picture for everyone to see. Some forums require that and it makes sense if they do. Just join in on conversations with questions and respond with your answers, ideas, and observations. Might as well have fun ... yes?!

Edit to do show this basket of shallots. By the way, do you see the lemongrass plants and the potted lemon verbena behind the basket?
