Hi all,

I have to use more images (that,sometimes,will be saved in another server for a backup),
so I wouldn't save them into the db to avoid having to sincronize and manage them twice.
By this need,I've tried to use the html to point directly on the image(<html><body><img src = 'C:\\myImage.jpg'></body></html>) but without results.

My question is:
Using the html,does exist a way to point to an external image?

if not:
Does exist another way to do this?

Thanks in advance,

Marco

Try this:

Code: Select all: <html><body><img src = 'file:///C:/myImage.jpg'></body></html>

are we talking here about a smart client? and then the c:\ where you talk about is the c: drive of the smart client? (so not a server or developer drive?)

@Joas:

It works,Thanks Joas!

@jcompagner:
Yes is the c: drive of smart client(for now I need only to choose the way that I have to take)

For who is reading this topic:
I have token another way because I have to work both with local and with remote files..I have token the related JSFile of myImage.jpg(using convertToRemoteJSFile) and I have convert it into a JSImage object by the code:

Code: Select all: var _file = plugins.file.convertToRemoteJSFile('/site_off.jpg') plugins.images.getImage(_file.getBytes())

After this I have resized the JSImage to create a miniature.

I have a new question: what is the best way to send the new miniature-image to the remote folder(/uploads)?
At now I'm using:

Code: Select all: plugins.file.writeFile('c:/mymini.jpg',_image.getData()) var _newFile = plugins.file.createFile('c:/mymini.jpg') plugins.file.streamFilesToServer(_newFile,'/mymini.jpg',null) plugins.file.deleteFile('mymini.jpg')

But I like to jump the "writeFile" passage and stream the new miniature directly on the server..
My problem is that the miniature is a JSImage object..How can I convert it into a JSFile without write it first?

Create a temp file on the client, write the JSImage to that, then stream the temp file. The important code bits:

Code: Select all: var image = plugins.images.getImage(file.getBytes()) // insert: do something with the image like resize it var temp = plugins.file.createTempFile(file.getName(), "jpg") plugins.file.writeFile(temp, image.getData()) var serverImages = [baseDirectory + directory + "/" + file.getName()] var monitor = plugins.file.streamFilesToServer([temp], serverImages, IMAGE_import_callback)
