In Chrome  you are supposed to be able to allow this capability with a runtime flag --allow-file-access-from-files  However  it looks like there is a problem with current versions of Chrome  37  38  where this doesn t work unless you also pass the runtime flag --disable-web-security  That s an unacceptable solution  except perhaps as a short-term workaround  but it has been identified as an issue  https   code google com p chromium issues detail id 379206

You have Two alternatives    First one is to create a ServletImageLoader that would take as a parameter an identifier of your image  the path of the image or a hash  that you will use inside the Servlet to handle your image  and it will print to the response stream the loaded image from the server    Second one is to create a folder inside your application s ROOT folder and just save the relative path to your images

This error means you can not directly load data from file system because there are security issues behind this  The only solution that I know is create a web service to serve load files

The concept of http location and disk location is different  What you need to do is    for uploaded file summer jpg move that under a known  to the application  location to disk  e g c  images summer jpg insert into db record representing the image with text summer jpg to display it use plain  lt img src  images summer jpg    gt  you need something  e g apache  that will serve c  images  under your application s  images  If you cannot do this then in step  2 you need to save somewhere under your web root  e g c  my-applications demo-app build images

Here is a simple expressjs solution if you just want to run this app locally and security is not a concern   On your server js or app js file  add the following   app use   local-files   express static          That will serve your ENTIRE root directory under  local-files  Needless to say this is a really bad idea if you re planning to deploy this app anywhere other than your local machine   Now  you can simply do    lt img src   local-files images mypic jps   gt     note  I m running macOS  If you re using Windows you may have to search and remove  C    from the path string

Do not use ABSOLUTE PATH to refer to the name of the image for example  C  xamp www Archivos images templatemo image 02 opt 20160401-1244 jpg  You must use the reference to its location within webserver  For example using       Archivos images templatemo image 02 opt 20160401-1244 jpg depending on where your process is running

sending tag  lt img src  c  images mypic jpg  gt  would cause user browser to access image from his filesystem   if you have to store images in folder located in c  images i would suggest to create an servlet like images jsp  that as a parameter takes name of a file  then sets servlet response content to an image jpg and then loads bytes of image from server location and put it to a response   But what you use to create your application  is it pure servlet  Spring  JSF   Here you can find some info about  how to do it

Many browsers have changed their security policies to no longer allow reading data directly from file shares or even local resources  You need to either place the files somewhere that your tomcat instance can serve them up and put a  regular  http url in the html you generate  This can be accomplished by either providing a servlet which reads and provides the file putting the file into a directory where tomcat will serve it up as  static  content
