I have made a picture drawing app according to a book.
However, there has been several issues and I wanted to upload the whole file but it seems like only pictures/photos are available to upload.
also if you are asking for help, I recommend you to make it as easy for others to be able to help you ...
You probably will get more feedback then...
which means in your case post a screenshot of your relevant blocks...
To download the aia file, upload it to App Inventor, open it, do some bug hunting for you, etc... this takes time, and most people will not do that...
Thank you.
In that case, export the project as an .aia fle, upload it onto the web somewhere like Google Drive or Dropbox, mark it as shared with the public, and post a link to it.
