[TYPO3-english] Replace images with ALT text

[Bob]

Hi all,

I have set up a page type for a low bandwidth version of a site. This 
successfully pulls in a different template with different style sheets, etc.

What I need to do next, is replace all images with their ALT text (for 
this page type only).

Can anyone give me any pointers on the best way to go about this?

Writing the PHP to do the replacements shouldn't be too tricky, but I'm 
not sure how to apply this function to the generated HTML. For example, 
the following *doesn't* work:

pageLo.10 = USER_INT
pageLo.10.userFunc = user_lowBandwidth->replaceImages
pageLo.10.pageContent < styles.content.get

Unfortunately, $conf["pageContent"] does not contain the HTML content - 
in fact, it seems to just contain "CONTENT" but I'm guess that it may be 
more complicated that that. (I'm sure this would be obvious to more 
experienced TYPO3 developers, but I'm still quite new to it!)

What the simplest way to process the generated HTML?

Thanks,

Bob
