Hell0 dmwesq,
Don't be thrown off by the book being about 1.6 and the current version of Joomla being 2.5. The instructions are exactly the same. 2.5 is a more stable version of 1.6. There are a few additions, but the basic procedures are the same.
Your questions are good ones and you are correct in what you learned. The module pulls the images from the public_html folder (the main directory) by design. So you do need to create subfolders manually if you want to change the location.
When you use the media manager it automatically uploads images to public_html/images, which is Joomla's default images folder. You shouldn't try to change that. You can create subfolders under images by simply adding a subfolder using the media manager, then opening that folder and doing the upload while the folder is open.
The only way to upload pictures anywhere other than the images folder is to use an FTP client or a file manager.
Here's a tutorial on a free filemanager you can use if you don't have access to one.
www.ostraining.com/blog/joomla/extplorer/ The confusion comes in because you are using a third party module. Third party modules have their own way of working and their own documentation. In the case of this module, the developers have made it easy by automatically making the basic path root/user/public_html/ so you would always be going to the correct main directory when using the module.
It is up to you to point it at your desired directory by adding to the path so it will pull the pictures you want. YOu do that by completing the path in the modules basic options. See the screen shot. That pulls from public_html/images/avatars
The avatars directory has to already exist. The module won't create it for you. The only folder that is created by Joomla when you install it for images is public_html/images.
When you are having trouble with a third party extension the best place to get help is the website of the developer of the third party extension. They have their own forums and documentation and usually know more about their product than people on the forum.
The website for that extension is
joomshaper.com and they do have a forum for getting answers on their products.
But I think you both got sidetracked from the main issue. Try to submit one question at time. There are really two problems here. One is trying to understand the file system, the other is about how the module works. It would be easier, and you would get faster answers if you try to get one question per post.
I read the ticket you posted. Steve is not the only person who can answer your questions. Our paid staff does not work on the weekends. Mark is an extremely knowledgeable volunteer, and I want to give him huge thank you for tackling this on the weekend.
And also thanks to Tessa, who is on our staff. We are closed on the weekends and they were very generous to use their spare time to answer off-hours. Please see the FAQ for a description of our support.
www.ostraining.com/support-faq/ Thanks for taking our class. And thanks for your persistence and patience. If you still have more questions. Please submit another post with your question. This thread is getting long and complicated and will be hard for others to follow.
Cheers,
Ed
