Thanks, you mean the images within the pages don't display?
If so, what setting do you have under the Preferences/Image Loading menu in IBrowse?
IBrowse v2.5 up has a number of internal image decoders according to the docs. I tested this by removing the GIF, JPG and PNG datatypes (the common images formats on web) from my Devs/datatypes drawer, browsing to the Aminet homepage, and I could still see the images (all the ones I checked are PNG); same with Amiga.org.
In summary, if I'm right that the issue is you can't see images in web pages it might not be caused by datatypes.
