if it helps - Roundcube Webmail seems to be able to show PNGs for FF and GIFs for IE


You could do this, as converting images to gif is easy. But whats nice about PNG you can use this software: http://brh.numbera.com/software/pnggauntlet/ to convert the PNG's to be even smaller, with no quality loss.

Update:
 
I've talket with our DOM-god about the PNG problem again and here are more details:
 
The problem is not the PNG itself. If you just use png-icons as replacement for gif-icons there should be no problems (should!).
 
If you use png images with alpha-transparency and animate them (fade-effect with javascript for example) the IE rendering engine slows down.
 
In fact: Everything dynamic (for example ajax) that changes little things (new background-color) forces IE to re-render the page and this seems to be the problem because the rendering of the alpha-channel pngs is buggy...
 
Hope this helps when you test V9.

Thats very interesting, we will have to certainly do allot of testing before making the final decision then. ]]> Wed, 07 Feb 2007 08:07:28 +0000 https://forums.webwiz.net/png-or-not-png-v-9-development-question_topic22549_post120310.html#120310 <![CDATA[PNG or not PNG? v. 9 Development Question : @borg: We developed a new tool...]]> https://forums.webwiz.net/png-or-not-png-v-9-development-question_topic22549_post120308.html#120308 Author: mxm.Kosh

@borg:

We developed a new tool some weeks ago. Because this was an internal tool we optimized it for IE7 and FF2. We also used PNGs for layout, icons and gfx-effects.

It was very cool to play with png - lot of things we can't do this easy way without png.

But we found a problem:
If you use a PNG-based layout and for example have a javascript fadein or similiar effect the IE rendering engine slows down very much. We tested this effect on a highend machine - same effect! There is no problem with firefox. For me it looks like they have implemented PNG support as easy they can - it's not fully implemented, it's like an overlay :(

So please be careful if you use PNG in V9 - we switched back to GIF and everything is fine now. The only problem is, that we have to create GIF-images for each color instead of creating one PNG with a transparency of 30%...

Just a info for you - whatever your decision will be, we'll use V9 anyway =)

PNG Alphachannel JS hack

I too now think that, yeah, go for it with the JS hack. 49.8% of my users are still using IE6 but as said, they need JS for the forum to work so we might as well push forward with a better graphics format.]]> Thu, 01 Feb 2007 09:08:03 +0000 https://forums.webwiz.net/png-or-not-png-v-9-development-question_topic22549_post120113.html#120113 <![CDATA[PNG or not PNG? v. 9 Development Question : &#034;With this in mind would...]]> https://forums.webwiz.net/png-or-not-png-v-9-development-question_topic22549_post120109.html#120109 Author: dfrancis

"With this in mind would this make a difference to peoples opinions on this?"
 
Yes... it changes my mind completely. You are right, if people are unwilling to enable JS, the forum is of no use to them anyway.
 
I retract my earlier reply and vote in favor of the change.
 
(Sorry, I know you mentioned the JS filter in your original post... I forgot to consider that when I formed my opinion... my mistake.)

Personally i think it's reached a point were great software developers should stop crumpling for the old browssers and lead the way in bringing new standards in.

To me also i think the javascript / IE filter would be a good way to start the cross over to PNG's

I have been using the PNG JS Filter Script successfully for some time now. If someone is no running JavaScript for whatever reason, tough, the forum won't run correctly anyway right? I would just draw a line and cut off those old browsers. /]]> Wed, 31 Jan 2007 19:45:42 +0000 https://forums.webwiz.net/png-or-not-png-v-9-development-question_topic22549_post120104.html#120104 <![CDATA[PNG or not PNG? v. 9 Development Question : Thanks for the feedback everyone...]]> https://forums.webwiz.net/png-or-not-png-v-9-development-question_topic22549_post120101.html#120101 Author: WebWiz-Bruce

Thanks for the feedback everyone it's very useful.

Some things that may help in the decision is that IE7 already has over 20% market share, however IE6 still has 56% but dropping each day as Microsoft force us to update with their auto updates etc.

For those using IE 6 or below javascript can be used to enable an IE built in filter that would mean PNG's would display correctly in IE 6 or below.

As javascript is required anyway to use Web Wiz Forums this would mean those users who couldn't view the PNG's correctly should be very few.

With this in mind would this make a difference to peoples opinions on this?

I've thought about this since it was posted and I would have to side with the gifs on this release. Version 10? Maybe change my mind. It's going to take a little while longer to wean people off of the older browsers. With some of the new features and security concerns of older browser versions, I think it won't take long, relatively speaking that is.
 
If version 9 is to be released any time in 2007, I would suggest that we stick with the gifs with plans for the png's later on. This issue may give rise to yet another option in the admin to chose the file extension of the standard images. (Just a thought.)
 
Anyway, I wanted to chime in and offer my opinion.
