Thanks for the Reply Steven.

The php solution is way beyond my understandings and ability.

I do think it is something that would be interesting for many people.  We all have images which we feel are stronger than others and would like to be sure that those will be seen.  Equally, we want to avoid repeat visitors always seeing the same initial images and consequently, not progressing any further through the galleries.  It is a conundrum.

I'll add it to the suggestions.

Thanks Steven.

Steven,

I'm a bit slow on updating you on this ... but the upshot is that the AdBlock people believe it is an issue with JBx and Safari.

I believe it may be an issue with all 3 running together.  Whichever it is, it would be good if your engineers could have a look into it prior to the next release.

Just tried a test with WowSlider and I'm getting the jitters as well. :(

Can I add some code myself via .htaccess Steven, or would the server side code overrule it?

Steven,

it's taken a lot of time of coming and going with my host's tech support, but essentially, the say it's a Safari bug.  I'm wondering if you agree, or if it could in fact be a Juicebox problem?

"I make some connection tests, and cache is well used :

By the Varnish server in front of your instance. But I'm not convinced that's the cause. And that's a matter on browser side.

According to the fact this trouble occurs only with Safari 8, I think that may be related to plugin version of this browser.

I tried with a Safari 8 without having trouble.

You can use this Website to check you plugins version :

But I'm affraid I can't help you more : trouble is on browser side."

Steven,

I just tried this again, to see if the sudden transition is fixed in 1.4.3 (sadly not).

I hadn't tried before to use the script in my embed code, but now that I do, it doesn't work for me.  I added it, as you suggest, below the embed code. would you mind taking a look to see what's wrong?

Show / Hide thumbs automatically.

As per this thread : http://juicebox.net/forum/viewtopic.php?id=1679

I would like to be able to have thumbnails visible on page-load, but then to slide out of sight after a set period.

Ideally, I would also like to be able to make them reappear with mouse-over.

Why :

I have found that visitors to my sites mostly never see, nor pay attention to the button bar.  They never click to show or hide thumbnails or run the slideshow. So it is up to me to find the best way to show my images, by taking care of that for them, whilst at the same time, gently pointing out how they can alter the viewing experience to make it either more practical or aesthetic depending on their preference or current needs (e.g. someone concentrating on the images themselves, or a client going through image choices).

Thanks Steven!

A last question ... is there any way to animate the show/hide by either slowly fading, or ideally, sliding thumbs out of view?  The on/off nature at the moment will, I think, confuse visitors.

Have you access to a Mac running Yosemite?  Could you check on that, for a site hosted on another server?  (Without using the .htaccess code, which is definitely not on my site.)

Steven,

apologies for slow reply ...

This is what they have said :

Hello,

"Do you think this could be an issue?"

Hard to say. I tried your Website from Iceweasel, Chromium, Opera, and doesn't see the 'stutter'.

Javascript is executed on client side, and server Apache cache is the same for all browser version. If that's happened only on Safari, seems to be related to this software. Maybe a cache settings on this browser.

We have a webaccelerator in front of the instances : a varnish server. That's maybe related to the retrieving images process.

Which type of web-servers have you been able to replicate the issue on Steven?  Any browsers other than Safari 8.x ?

Wow!  Nice work Steven.  That's some pretty intense bug hunting there.

I'll be really pleased when I can publish my galleries, secure in the knowledge that they're being viewed in the best possible way.
