Images don't show after the 49th image

[jtweeks]

I'm a new user to this forum and I have recently encountered an issue when creating an epub file with Sigil 1.8.0 on a Windows 11 desktop.
I have been using Sigil for several years, mainly to edit and correct existing epub files.
Currently, I am creating a new epub file that will contain about 60 different images. The first 49 images display in the document without issue. However, subsequent images, even re-displays of previously displayed images, do not display.
I am using the following code to display images - <p class="aligncenter"> <img src="../image.jpg"/> </p>
With the following in my main CSS file - .aligncenter { text-align: center;}
Any help would be greatly appreciated.

Probably incorrect links? Hard to tell without more info. Does it only not display properly in Sigil? Does it pass epubCheck? Can you see the images in another reader?

I would run the epubcheck plugin and report its errors here. That should tell us.

Thank you KevinH for your quick reply. I did download the epub file to my phone which has Lithium installed. The epub showed fine except the same images did not show. I have also run the epubCheck as you suggested which got the following results which I do not understand. Can you help to interpret?

Do you have Java installed?

If you open a command prompt and enter java -version, what is the response?

Here's what I see on Windows 11:

java -version
java version "1.8.0_311"
Java(TM) SE Runtime Environment (build 1.8.0_311-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.311-b11, mixed mode)

If that works, you might want to check the troubleshooting information in the epubcheck plugin for Sigil thread.

[KevinH]

Yes. The plugin needs you to install java to get it to work. Once working, it will report any actual errors in the epub.

Also another common problem is using mixed case. If an img tag the src attribute is case sensitive. That means ../Images is not the same as ../images

This holds for filenames as well.

Try deleting the one of the img tag links that does not work. Then use Sigil's Insert Media toolbar icon, to select and recreate the proper image link.

[jtweeks]

Yes java is installed:

C:\Users\jtwee>java -version
java version "1.8.0_311"
Java(TM) SE Runtime Environment (build 1.8.0_311-b11)
Java HotSpot(TM) Client VM (build 25.311-b11, mixed mode)

I don't think it is a mixed case issue, as I can view the images earlier in the text, just not later in the document. Like you suggest I can copy the code from an area that shows the image to later in the document, and the image does not show.

Looking at your output, that appears to be from a 32 bit version of Java. You may want to install the 64 bit version of Java.

You may also want to check message #412 in the epubcheck plugin thread about forcing the path to the java executable. The disadvantage to this is that you will need to update the path any time that Java is updated.

For the 64 bit version of Java 1.8.0_311, the path would be something like:

"java_path": "C:/Program Files/Java/jre1.8.0_311/bin/java.exe",

[KevinH]

That can easily happen if the later xhtml files are not in the same directory as the earlier xhtml files meaning the url must be different to find the image file.

Go into Sigil Preferences and enable showing full book paths in BookBrowser and then post a screen cap of the resulting BookBrowser window so we can see the actual paths used for the xhtml file and the image file for one instance it does not work.

Using Sigil insert media tool can be helpful as it will always properly create the proper url for wherever you put the files inside the epub.

[KevinH]

And DNSB's advice to set the java path for epubcheck is a very good one. Please try that as epubcheck will check for many many common epub issues.

[jtweeks]

Never mind - I found my issue.. It was all user error!!!

Care to share, in case others run into something similar?
