I have now tried for the first time to display images larger than 1024x768. I proceeded as described for the JuiceboxBuilder-Pro in the help. I created image sizes in Medium 1024x768, Large 2048x1536 and Small 800x600 via the builder and then uploaded them. On my IMAC M1, this also looks quite good in the Safari web browser. I can see that the large images are accessed when I click on the Expand Gallery button and also select Hide Thumbnails. However, when I do this in the Microsoft Edge browser or Crome, the behavior is not the same. The image is only displayed slightly larger. And if I also click on Hide Thumbnails, the image remains the same size and only moves up to the position of the thumbnails. I'm a bit unhappy about this because I can't see what I might be doing wrong. I can only assume that there is a limitation in the basic settings. However, if I have read this correctly, the size should not be set to a fixed value, but to AUTO. I would therefore ask you to take a look at this web gallery. I would like to be able to display the images larger in the future, but I need to be sure that it works.

Hello support team,
I have with JuiceboxBuilder-Pro already 33 galleries in all web browsers without error operational. In my workplace in a big company I can appeal under Windows XP and IE 8 for a few weeks of galleries no more. The index.html page is loaded, however, it seems thus as the JAWA Script juicebox.js is not loaded. The monitor remains an empty page. An error message is indicated: " The web page contains error and possibly does not function properly " ´ juicebox' is undefined, index.html, line 27 - code: 0 character 4. This happens in the company intranet with all my index pages. Is there a basic error in the html construction? If so where this could be. Can the execution of the juicebox gallery be blocked by the internal firewall? Example: http: // www.profi-diver.de / Superior_Producer / index.html or http: // www.profi-diver.de / Curacao_Schwarmfisch / index.html

Thank you for an answer.

Hello Steven,

thank you for helping me again. Yes, you are right, the image scale was not configured. Now, the gallery works how it should be and I can start with my project.
Thank you.

Hello Steven,
thanks for your very quick answer. Your tip to the wrong authorizations led me to the success. The folders images and thumbs had the authorization 644. Now after conversion on the authorization UNIX 755 the Gallerie can be indicated. I thank quite warmly for this quick help.
Because now also IPAD users should look at this page after the completion, I have checked as itself the page on the IPAD images. Now here arises a new problem. The main image is to be seen only to a third. The main image is imaged only proportionately. I suppose that the settings are not right in de config.xml here yet. Therefore, I request your help again to settle also this mistake. In the Apple safari of browsers the page looks in such a way as I have erected them. Already in the Internet Explorer the image seems pulled very much in the length. The representation should be maximum 800x600 px. The images are not indicated proportionally to the window size, the watermark (Michael Falldorf) is partially absent. Google Chrome shows the same problem. Also a gray beam appears in the Internet Explorer before the heading and <back> button. Firefox indicates the page normally.  What is wrong now again?
I hope, you understand all of my very simple english conversation.
Thank you

Hello Steven,

since a few days I try to find desperately the mistake which appears if I have the page uploaded to my Provider.I already have many tries undertaken to invest directly links and all the other things described here. Unfortunately, I do not get further and please you around help. Please, have a look to: http://www.m-falldorf.de/Lembeh_Strait/. The gallery on the page works (click left or right or on the thumbnails), but the images are not visible. What is wrong?

Thank you for help.
