Navigation button fly over images to their place

Hello
I am quite happy with the Hot Photo Gallery Plugin.
It might be very simple, but does what it should - so perfect! Thanks for this application!

But unfortunately I get a very strange effect if I open any picture. If I click on a image it pops up as it should. BUT the navigation buttons move around over the image to their actual place they should belong.
The [Prev] button flyes down from the top of the image to its place.
The [Next] button moves from the middle/top of the image to its place on the right.
Everything works as it should, but this effect is not very professional looking.

Actually I tested it with several browsers.
In Opera and Firefox the effect as described above happens. In IE both buttons behave like explained for the [Prev] button.

Where might be the error?
Here my site (klick on one of the lowest 4 pictures):
iselieng.ch/cms/index.php/windschutz/faltbarer-windschutz

Thank you in advance for your support and help!

It looks ok to me chrome,FF, IE10, IE10 compatibility

Thanks for the replay!

So if you open my site in any of your browsers and click on a picture the buttons stay always in the same position when you click though the pop-up gallery?

I have tested it again with the FF 19.0.2 (latest version) and also the latest version of Opera and Chrome. Still the same in all browsers.
Here a video about how it looks at the computers i tested with:

Any idea?

Add this some-ware in your styles:

a#lightbox-nav-btnPrev,
a#lightbox-nav-btnNext{
text-decoration: none;
-webkit-transition: none!important;
-moz-transition: none!important;
-ms-transition: none!important;
-o-transition: none!important;
transition: none!important;
}

Awesome! Thank you so much!
It works perfectly now.
(Unfortunately I do not see the buttons on my tablet browsers, but this is less important)

Might I just ask, if you know, if it is possible to add the Hot Photo Gallery Plugin a secound time to my joomla, so that I can use different settings (# images in a row, colours,...)?

You can add it multiple times. On tablets buttons don't show because their visibility depends on mouse position. You can force then be always visible:

a#lightbox-nav-btnPrev{
display: block!important;
height: 370px!important;
background-image: url( iselieng.ch/cms/plugins/content/photogal...ightbox-btn-prev.gif )!important;
background-position: 0% 15%!important;
background-repeat: no-repeat no-repeat!important;
}

a#lightbox-nav-btnNext{
display: block!important;
height: 370px!important;
background-image: url( iselieng.ch/cms/plugins/content/photogal...s/lightbox-blank.gif )!important;
background-color: transparent!important;
background-repeat: no-repeat no-repeat!important;
}

add that anyware in your style css files.
