Faviconic Revisited

The Favicon Support Chart has been updated to reflect changes in newer versions of Safari and AOL along with needed corrections due to an improperly formed multi-res favicon. Check it out and let me know what you think.

A couple things brought me back to the Favicon Support Chart this week. The first was a Bugzilla update on a Webkit favicon-related bug I had filed some time ago, and the second was a feature I discovered in Leopard's updated Preview application; exploring the first while leveraging the second exposed a problem in my original tests.

Turns out the multi-res favicon I had created was flawed, invalidating some of the multi-res results. I exposed this problem when I decided on a whim to try and load the favicon into Preview, which can display all the icons at their assigned bit-depths.

Doing so, I noticed that Iconographer had saved the 32-bit icon over the 8-bit, and nothing I could do with the editor seemed to succeed in making an 8-bit icon "stick". Iconographer no longer appears to be in development, but I remembered noting a favicon Photoshop plug-in in the original favicon entry and decided to try Telegraphic's ICOFormat and ICOBundle. ICOFormat is a donationware plug-in for all versions of Photoshop which extracts, edits and saves individual favicons, and ICOBundle is a free drag and drop utility that combines individual favicons into a single multi-res version. Both are cross-platform [mac/win], released under the GPL, and rock.

The screengrab animation below shows Leopard's Preview displaying the corrected multi-res favicon.

The now properly formed multi-res favicon behaved differently in some of the browsers that previously exhibited issues; re-testing followed and I believe the latest version of the chart is better for it.

Hope some of you find this useful. For more in-depth favicon information, check out the original entry: Faviconic.
