Here’s how I post pics from I phone and computer. This site to my knowledge does not save them like photobucket but I have no idea.
Go here
https://postimages.org/
Then hit choose image.
You can then select:
Take photo
Photo library
Or browse
When you find the one you one hit the pic and a check mark will appear. You can do multiple at one time but I usually do one at a time. Then hit done top right corner. It will then upload. Below the pic will be multiple selections. Hit hot link to forum on the right side there is a little symbol that when you hit it will say copied.
Come back to aldeer and hit paste in the text box and there you have it.
