I am running a web server and storing all my photos at a folder called photos. Now I want the android application to list all the photos under that particular folder(It can be a slide show or a grid view). I know how to load an image from a url . But I am really unsure about how to view all the images stored on a folder. Could someone please point me in the right direction.
Refer this for load web images in gridview
And this to load images from web by lazylist.
To get list of images from your folder. You need to read all file names in that folder by using FTPClient and put the filenames as url in the above method.

I have a folder on my computer with many images. I want to have my app be able to load all of these images into a View. I have no problem loading one image from its url (using Picasso) but I want to know how to load a folder of them (i.e the amount of images may change).
I was thinking that I could use a Google Drive public folder to store the images, but how could I get the images from within the folder (i.e if I had the folder's URL could I use Java to "open and look inside" it)? Is there a better (and free) way than Google Drive to store the images? Maybe an imgur album or some kind of free server hosting service?
You can use Firebase or Alternative use is Imgur . You store images there and the links of images tou can store in a db (sql Lite) and just add connection of db in main.activity Here you can learn how
You should consider using Firebase for this. Upload your Images in the Firebase Storage and store the link in the database. Once done, you can show all the Images in your app and also dynamically add the images.
I have list of urls relevant images loaded on to a server, i need to show thumbnail of these images in the ListView with out download of the image.
Images will be downloaded on next screen when user go in details page.
Find out who manages the server. Contact that person. Ask them "hey, can you please give me alternative URLs for these that will return thumbnail images"? If you get the alternative URLs, use them with your favorite image-loading library to get the thumbnails.
Otherwise, it is impossible to get a thumbnail for an image that you do not have.

Try it with Cache? Best way to do this:
http://www.androidhive.info/2014/05/android-working-with-volley-library-1/
Volley gives you a NetworkImageView, this is a "normal" ImageView, but you can give it a URL and volley will do all the rest for you (download, or load from cache, if already loaded).
So on my android app, it uses webview to connect to my website and display the index.php file that is on there. That file takes images from a directory on my website and displays them. The problem is that it takes forever for the images to download onto the app! Is there a way I could get the images pre-loaded into the application so that it still runs the PHP like it is supposed to but it doesn't download the images from my website? The images would have the same name and everything. Think of it as having the images cached before downloading them. Is there anyway to do that?
I want to list files from url. For example, there are some jpeg files inside http://www.example.com/jpegfile/ that i want to list these files on my android app.
I know how to list files inside the phone, but i dont know how to list from url.

Well, before you can list your files from URL, you need to download them. Check this link, it will help you properly download your images, then you'll have to just show them where you want.
