Equation changes size on mouse over

Hi,

I donated towards your equation editor project a few years ago but never really ended up using it. Now I'm investigating the possibility of putting latex equations inline with my text and thought I'd give it a try again.

I followed the instructions on this page, http://www.codecogs.com/latex/htmlequations.php, and linked to the javascript file in my header, but there seems to be a strange problem when viewing in FireFox (ironic, since it's usually IE that causes problems..). When I move my mouse back and forth over the equation, it changes size. It's kind of hard to explain, but if you'd take a look at my test post, here: http://www.roboticsguy.com/test-post-with-latex, and let me know what you'd think, I'd be grateful.

Thanks for your time,

Nathan

Hi,

This effect is based on our trials with using svg images whenever possible. This effect is actually by design, as it allows people to see the equations in an enlarged form. Handy for superscripts etc. But this also demonstrates the fantastic potentials that exist with svg. Unfortunately IE don't support svg so with them we still embed gifs.

We have been waiting for feedback on this, so if your unconvinced or feel it could be done better, then please let us know. Its a very simple modification at our end to change the effects.

Regards Will.

We've looked more at the issue. The fact this effect doesn't occur with the first image is worrying. We've therefore turned it off for the mean time. You'll have to reset your browser cache, then everything should work as expected.

Thanks Will! It works great now!

Does rendering the equations put a lot of strain on your server? I probably won't have more than a few dozen right now, but I don't want to cause any problems!

Hi, our service is very efficiently implemented so a few dozen equations won't have any impact, though it depends on your users base. 1M people looking at a few dozen equations each day would become a problem !! Currently our free usage is limited to 3000 per day, the to latest of on this see http://www.codecogs.com/latex/usage.php
