Buggy Linux Browsers

On my system I had some web pages that would crash Mozilla. I downloaded and install FireFox 1.0PR and it works fine with these same web pages. So I think it is something on you machine. What I don know. But try installing Firefox it may fix you problem and it runs faster and better than Mozilla anyway.

Thanks for all your replies. I would be interested in knowing what size file of my images from the pop-up pages you were able to capture and how you did it. Please Anthro or others try if you want to download and enjoy the pics. I looked at what got cached in IE on XP and it was only 200k. The real file is much larger. I am not concerned with cache files as much as hi-rez printing files.

I'll try Firefox if there is a rpm instead of a tar file. I have been messing around trying to upgrade my modem drivers from a tar.gz and having to edit the make file etc and this is exceeding my week old Linus skills.

Are the popup settings refered to system settings or browser speciific? I did find global javascript settings in controlcenter/internet and everything is enabled.

this will get you to an RPM for FireFox 1.0PR ftp://ftp.suse.com/pub/projects/mozilla/firefox/1.0PR/

I downloaded Fgallery9-7.jpg just to check and it shows as 389.1KB on my system.

In Mozilla go to 'Edit -> Preferences -> Advanced -> Scripts and Plugins' and untick box for 'Enable JavaScript For' to disable JavaScript and render your protection useless.

For Pop-Ups go to 'Privacy and Security -> Popup Windows' to control your pop-up handling.

For Firefox both above are under 'Edit -> Preferences -> Web Features'

Opera has it in similar fashion.

In IE method is similar but you need to dig a bit deeper (don't remember exact path from the top of my head now) execpt for pop-up blocking that is not possible unless you got SP2 installed.

Forgot: If you install Web Developer toolbar for Firefox and Mozilla, procedure is even easier, just 2 clicks away on your toolbar.

After all the useful feedback I took the site down till I can find better image protection, even if it means burning a watermark in in PS. In IE on XP all I had to do without disabling anything is simply left click on the image and drag it to the desktop and there was the full size image. There was watermark feature I enabled but this did not imbed into the image and the watermark file as well could be dragged to to the desktop if you clicked on it. I guess the right click and dummy watermarks might provide the most basic "fake" protetection.. Is is such as thing as on-the-fly real watermark protection through scripting, I assume there is not?

Check the Digimarc's offerings, they are the best in watermark protection technologies. Other choice is for you to embed text 'sample' or similar to each image (using transparency so that it doesn't distract the image completely).

You can also use PHP, Perl or any other server side scripting language to create them on the fly and modify those to your requirements but even watermarking can be wiped from the image after it has been saved few times in different formats and modified a bit and embedded text can be 'erased' with colour filtering etc. Only display low-resolution ones on your site with above mentioned protection.

Remember that you can only protect the theft from casual users, not determined ones.

If you are selling images, _never_ put the originals on the web (don't even store them on the server unless you got extremely high demand for them and can afford to separate file server and extended security measures), only deliver them with the license _after_ you've received payment.

I did call Digimark. As far as I can tell what they offer is a way to track you images and hopefully contest legally if you find someone using your images. What Digimark does not do is imbed anything that in any way prevents a thief from printing or otherwise distributing your image files. Digimark may help in tracking and legal battles but not in actual reproduction. It seems the only way is to burn in raster my logo or copyright info into the images on the server. This would also protect from ISP employee ripoffs.

Maybe you've solved it by now or given up, but I just found this thread and have the same problem - I reckon there is a problem with Konqueror/KDE (even 3.3.1). I have registered a bug with KDE, that has been confirmed, that it doesn't work with certain framed sites , esp where they calculate the pages you want from Java.
(http://bugs.kde.org/show_bug.cgi?id=91236)

However, no evidence that it will get resolved as it seems to "get no votes" ?!

Its a shame, because IMHO if you can't trust a browser to work reliably/display everything on a page it might as well go in the dustbin!

I may try firefox someday soon.

Every time you click one of those pictures that is breaking your browser, it calls this function. I notice they are using window.open(), which is pretty common of course. I found on Linux Mozilla Firefox 0.8 that window.open() will bring down the whole browser.

Go to mozilla.org and get their latest version - should be 1.0. It comes with a nice easy installer. The window.open() problem appears to have been corrected in this new version; I haven't poked through their list of bug fixes, but I also no longer have the problem.

[edit: fixed typo and added comment below.]

With all due respect to those who like it, javascript seriously sucks.

One more thing I should add: the function has a browser sniffer - and not a very good one. So it's not bothering to detect for more obscure browsers, which would explain why Konqueror is throwing up errors.

[more ranting]

The reason javascript is such garbage is that there are many different implementations of the DOM (document object model), which makes it nearly impossible to design a web page that gets along with everyone's browser. In the function I posted above, they are using javascript to write out the HTML, which drives me absolutely nuts. This type of thing should be handled on the back end by an HTML-generating scripting language.

As you can see, their browser sniffer only bothers checking for IE > v4. So they banked on everyone using IE (which still enjoys over 90% of the web browser market), and must have felt it was ok to potentially break other browsers. Unfortunately, a very common mentality.
