Why can t I do img src C localfile jpg

Question

It works if the html file is local  on my C drive   but not if the html file is on a server and the image file is local  Why is that   Any possible workarounds

User · Answer

Honestly the easiest way was to add file hosting to the server.

Open IIS
Add a Virtual Directory under Default Web Site
- virtual path will be what you want to browse to in the browser. So if you choose "serverName/images you will be able to browse to it by going to http://serverName/images
- Then add the physical path on the C: drive
Add the appropriate permissions to the folder on the C: drive for "NETWORK SERVICE" and "IIS AppPool\DefaultAppPool"
Refresh Default Web Site
And you're done. You can now browse to any image in that folder by navigating to http://yourServerName/whateverYourFolderNameIs/yourImage.jpg and use that url in your img src

Hope this helps someone

I see two possibilities for what you are trying to do     You want your webpage  running on a server  to find the file on the computer that you originally designed it   You want it to fetch it from the pc that is viewing at the page    Option 1 just doesn t make sense     Option 2 would be a security hole  the browser prohibits a web page  served from the web  from loading content on the viewer s machine   Kyle Hudson told you what you need to do  but that is so basic that I find it hard to believe this is all you want to do

I have tried a lot of techniques and finally found one in C  side and JS Side  You cannot give a physical path to src attribute but you can give the base64 string as a src to Img tag  Lets look into the below C  code example   lt asp Image ID  quot imgEvid quot  src  quot   quot  runat  quot server quot  Height  quot 99px quot   gt   C  code  if  File Exists filepath                                                                byte   imageArray   System IO File ReadAllBytes filepath                                   string base64ImageRepresentation   Convert ToBase64String imageArray                                   var val     quot data  image png  base64  base64ImageRepresentation  quot                                   imgEvid Attributes Add  quot src quot   val                                  Hope this will help

IE 9   If you want that the user takes a look at image before he posts it to the server   The user should ADD the website to  trusted Website list

If you re deploying a local website just for yourself or certain clients  you can get around this by running mklink  D MyImages  C  MyImages  in the website root directory as an admin in cmd  Then in the html  do  lt img src  MyImages whatever jpg  gt  and the symbolic link established by mklink will connect the relative src link with the link on your C drive  It solved this issue for me  so it may help others who come to this question     Obviously this won t work for public websites since you can t run cmd commands on people s computers easily

Browsers aren t allowed to access the local file system unless you re accessing a local html page   You have to upload the image somewhere   If it s in the same directory as the html file  then you can use  lt img src  localfile jpg   gt

Newtang s observation about the security rules aside  how are you going to know that anyone who views your page will have the correct images at c  localfile jpg  You can t  Even if you think you can  you can t  It presupposes a windows environment  for one thing

what about having the image be something selected by the user   Use a input file tag and then after they select the image  show it on the clientside webpage   That is doable for most things   Right now i am trying to get it working for IE  but as with all microsoft products  it is a cluster fork

It would be a security vulnerability if the client could request local file system files and then use JavaScript to figure out what s in them   The only way around this is to build an extension in a browser  Firefox extensions and IE extensions can access local resources  Chrome is much more restrictive

we can use javascript s FileReader   and it s readAsDataURL fileContent  function to show local drive folder file  Bind change event to image then call javascript s showpreview function  Try this -   lt  doctype html gt   lt html gt    lt head gt       lt meta charset  utf-8  gt       lt meta name  viewport  content  width device-width  initial-scale 1 0  maximum-scale 1 0  user-scalable no   gt       lt meta http-equiv  Content-Type  content  text html  charset utf-8  gt       lt title gt  lt  title gt        lt script src  https   cdnjs cloudflare com ajax libs jquery 3 3 1 jquery min js  gt  lt  script gt        lt script type  text javascript  gt      function showpreview e            var reader   new FileReader            reader onload   function  e                    previewImage   attr  src   e target result                       Imagepath files 0  is blob type         reader readAsDataURL e files 0               lt  script gt   lt  head gt   lt body  gt       lt div gt       lt input type  file  name  fileupload  value  fileupload  id  fileupload  onchange  showpreview this   gt       lt  div gt       lt div gt           amp nbsp       lt  div gt       lt div gt       lt img width  50   id  previewImage  gt       lt  div gt   lt  body gt   lt  html gt
