ASP Linking to dynamically generated images...

humbert

I'm sure there's a perfectly simple way to do this but I can't seem to find it.

I've created a page(i.e. GetImage.aspx) to return an image based on the request query with works fine in image tags with

<img src="<%# DataBinder.Eval(Container.DataItem, "URL") %>" border="0"/>

but if I set it as a link with

<a href="<%#DataBinder.Eval(Container.DataItem, "URL") %>"></a>

it displays the image as text.

Is the only solution to point the href to a page that generates some html too, with image tags setting the image source to something like GetPage.aspx again.

The purpose is to have a thumbnail link to the full sized image. Oh and I'm using a repeater control in case that's not obvious.

Any help appreciated. I'm quite capable at putting the code together but don't have a lot of knowledge is this area so I'm pretty clueless about common practices.

Try using img tags rather than hyperlinks.

I'm not totally sure I understand, do you want
<a href="<%#DataBinder.Eval(Container.DataItem, "URL") %>"></a>
to display an image which is also a hyperlink? Or do you want it to display a link that when clicked on brings you to your aspx page which is in fact in image?

If it's the latter I presume you are already writing the image back to the response object since it's showing up when you use the image tags. You might just need to set the response objects content type if you're not already, I think you want to set it to "image/jpeg" (if you're returning it as a jpg image of course)

Thanks, I wasn't setting the content type. Once I did it worked perfectly.
