.png displaying correctly in IE8,Avant BUT NOT in Firefox, Chrome, or Opera

Hello everyone,

Attached below is a textbook exercise on the topic of “using tables for page layout”

Everything displays correctly in the IE8, Avant and Maxthon browsers but the topright.png is NOT displaying correctly in Firefox, Opera, Safari or Chrome.

Any ideas of why this is occurring?

Any images I use I always save as jpg and sometimes gif.
Anyone knows, why would you want to use a png instead of a jpg?

If you save your image as a jpg instead of png, does it then work in the other browsers?

I will give it a try… Thanks for the suggestion… all the other .pngs display correctly in all browsers

Hmmm, you have a typo in rounded.css:

no-repat top right -> no-rep[e]at top right

That will solve your main ‘topright.png’ missing issue.

Well (not including the banner); those eight superior lossless PNG-8 files can produce a far smaller image size than a lossy (JPG at around 80% quality).

The eight files saved as: JPG (2,790 bytes) 80% save quality.
The eight files saved as: PNG (1,969 bytes) PNG-8

Optimised (eight files) PNG-8 (1,504 bytes). So you can see the JPG was overkill since the images usually had less than 50 colours and very little gradient ‘horses for courses’ and PNG won yet again. Obviously these are just using the above files so you will get slight differences depending on settings.

Thank you very much for the assistance, xhtmlcoder.

The table is now displaying correctly in all browsers.

No problem. I just looked at that line and noticed a misspelling.

Remember, you can always use the W3C CSS Validator too; it may be of help in the future.

Thank you

No need to thank me twice but much appreciated. :slight_smile:

So the problem wasn’t to do with the PNG image at all, but rather default browser behaviour. Interesting turn around.
