Subject Re: [Question] Image path - Best way?
Date Sat, 27 Sep 2003 08:55:18 GMT
Struts has a tag that will put the context path on the front of the src URL
for you. Here's an example:

<html:img page="/images/leiste_oben.jpg" width="430" height="80" border="0"
alt=""/>

If you want to reserve the option to internationalize what image gets
displayed, Struts has good support for that, too. For instance, if you have
a button image with some text on it, and you want to be able to show
different images for different languages, you can put the image path in the
ApplicationResources.properties file and use something like this:

<html:img pageKey="button.clickMe.src"/>

You can also use the altKey attribute of the <html:img> tag to
internationalize the ALT, um, thingy.

<html:img pageKey="button.clickMe.src" altKey="button.clickMe.alt"/>

In your base ApplicationResources.properties file, you might have something
like this:

button.clickMe.src=/images/button_clickMe.jpg
button.clickMe.alt=Click Me

You can override these values for other languages in locale-specific
versions of the ApplicationResources.properties file.

One thing to be careful of with specifying images this way is that if you
set the size in the <html:img> tag (which is a good idea to speed rendering
performance in the browser), make sure that all the images for a given
button match the size that is specified.

They don't exist now, but it might be useful if heightKey and widthKey
attributes were added to the <html:img> tag to allow those to be looked up
in the properties file as well. That way you could specify different sizes
for the images if they happen to be different for different locales.

For complete documentation, see the online docs for <html:img>, here:
