Re: Dynamically loading image
Hi, I have only tried to load image from URL http://www.yiigo.com/guides/csharp/how-to-download-from-url.shtml with the help of some toolkits. You can also google it and choose one to help you. I hope you success. Good luck.

Re: Dynamically loading image
Thanks for the help guys.
I've got it all working correctly now. For other people's future reference.
I think this is the page that Igor was referring to which I pretty much
copied : https://cwiki.apache.org/WICKET/uploaddownload.html
I am retrieving the images from a db as a byte array
//heres a simplified version of my code. Hope this helps someone!
//this is the class that serves up the images
public class ImageResource extends DynamicWebResource {
private static final long serialVersionUID = 1L;
public ImageResource() {
super();
}
@Override
protected ResourceState getResourceState() {
ValueMap params = getParameters();
String id = params.getString(id);
if (id.equals(image1)) {
//show image 1
return new ResourceState() {
@Override
public byte[] getData() {
//get the image1 from server
return image;
}
@Override
public String getContentType() {
return image/jpeg;
}
}
} else (id.equals(image2)) {
//show image 2
return new ResourceState() {
@Override
public byte[] getData() {
//get the image2 from server
return image;
}
@Override
public String getContentType() {
return image/jpeg;
}
}
}
}
}
//this is how I access the image from wicket
add(new Label(profileImage, ) {
private static final long serialVersionUID = 1L;
@Override
protected void onComponentTag(ComponentTag tag) {
ResourceReference imageResource = new
ResourceReference(imageResource);
tag.put(src,
RequestUtils.toAbsolutePath(getRequestCycle().urlFor(imageResource).toString())+?id=image1);
super.onComponentTag(tag);
}
});
//and this needs to be added to the wicket application init method
getSharedResources().add(imageResource, new ImageResource());

Re: Dynamically loading image
Where are you storing the image, on the file system, classpath, database...? From: Matthew Goodson matt...@spidertracks.co.nz To: users@wicket.apache.org Date: 11/29/2010 10:12 PM Subject:Dynamically loading image Hi all, I'm needing to generate the url to an image dynamically on the client. i.e. I want to be able to chuck a generated url (e.g localhost:8080/images?imageId=blah) into the src of an img which would then go off and hit a wicket page which returns the binary data for the image. I'm not really getting anywhere by myself. Does anyone have any pointers?! Hope that makes sense.

Re: Dynamically loading image
there is a wiki page that explains how to serve images...search for it, i think its called uploade/download or something like that. -igor On Mon, Nov 29, 2010 at 7:11 PM, Matthew Goodson matt...@spidertracks.co.nz wrote: Hi all, I'm needing to generate the url to an image dynamically on the client. i.e. I want to be able to chuck a generated url (e.g localhost:8080/images?imageId=blah) into the src of an img which would then go off and hit a wicket page which returns the binary data for the image.
