kinglozzer opened a new issue #1902: Images being rewritten despite image_preserve_urls being set
URL: https://github.com/apache/incubator-pagespeed-mod/issues/1902
 
 
   Hi,
   
   I’ve been trying to enable filters one-by-one for my application in the least intrusive manner possible. So my current configuration is:
   
   ```
   ModPagespeed on
   ModPagespeedRewriteLevel PassThrough
   ModPagespeedEnableFilters in_place_optimize_for_browser,image_preserve_urls,convert_jpeg_to_webp
   ```
   
   Images are re-encoded to webp in-place as expected, but part of my `<picture>` elements are still rewritten. E.g:
   
   ```html
   <picture>
   	<source media="<query>" srcset="<path-othersize>.jpg">
   	<img src="<path>.jpg" alt="">
   </picture>
   
   gets rewritten to
   
   <picture>
   	<source media="<query>" srcset="<path-othersize>.jpg">
   	<img src="<path>.jpg.pagespeed.ic.0UtHAEiYYU.webp" alt="">
   </picture>
   ```
   
   I thought `image_preserve_urls` was intended to prevent this sort of URL rewriting, am I misunderstanding that filter?
   
   Thanks!
