Webdeploy not uploading all files

Hi,
I'm new to the Visual Studio and C#/.Net and was wondering why web deploy doesn't upload all my files to the remote folders. I notice I am missing some image files, aspx files and such in the remote folders despite them being present in the solution explorer.
Is there a way for web deploy to upload all the files in the solution explorer. I'm using Visual Studio 2015. Maybe I'm not saving the project right or missing a publishing setting? Thanks
