Yes, both pictures and footnotes can be exported in the ePub file format. If you still have Ulysses 2.1.3, you can export footnotes as endnotes, if you already have Ulysses 2.1.4, they are exported as an ePub footnote (like this one).
The manual for ePub export should explain how to insert pictures and footnotes quite nicely.

How did you reference the footnotes/images in the notes? For footnotes, it should be {{footnote1-You footnote text}}. For images, it's [[image1-the actual image-an image description]]. Please note the last part is required for Web Export and ePub export: you need to add a textual description to the image which is displayed below the exported image. If you don't want that, contact us directly at support@the-soulmen.com and we can set up something for you.

Localization should not have an impact on the export functionality of Ulysses. In fact, I just tried exporting an ePub with a picture inside using the german localization of Ulysses and the image was included in the exported ePub. I think the easiest would be to send us the Ulysses project (or just a minimal sample containing the images/footnotes that are not exported).

Thanks a lot, I'll take a look at it!

Where is the difference between these paths?!?

I have only:

…/Exporter/LaTeX.

Ah, now I can see the difference. ;-) The middle of the path is different.

Okay. I will do so.

What part of it is not working? Does Ulysses not launch? Does ePub not show up in the Web Export? Does the export fail?

Hello I'm taking over :-)

Just to make sure I understand you correctly, I'm asking again.

To get images and footnotes in ePub to work, first go to the Inline Style preferences via Ulysses>Preferences>Inline Styles and add a style for images and one for footnotes. Then use this tags to mark your image and footnotes. Second, in the exporter, set your Inline Styles with the Description "Image" to the the Action Image and set "Footnotes" to Footnotes.

Now the export should work in the wished way.

I did an ePub export myself with the inclusion of pictures and footnotes, which worked as expected. Here is my document if you'd like to try it with that one: http://cl.ly/371H0W3v0O1Z

I hope this helps.

All the best, Vivien

But there is a new question: Is its possible to change the text „Image 1“ to e.g. „Formula 1“ or the german „Abbildung 1“?

Do you want to have image headings/descriptions in the exported ePub? (If you don't, you can use the custom template I described above)
The thing is, with the current approach, you cannot export to both PDF and ePub since the description text will show up in the exported PDF, this is why I provided you with the ePub template.
If you want to have image headings in the ePub, I could provide you with such a template. However, does "Abbildung" alone suffice for you? What about "Formel" or "Tabelle"?

And is it possible to center images? on the page?

They should be horizontally centered in iBooks. Are they not?

My ePub looks as follows in iBooks: https://skitch.com/e-gootz/ecwky/photo
(For this, I added a description to the image note, as in
[[formel1-IMAGE-A description for the formula.]])

Like that?
I updated the custom WebExport template for ePub export (similarly to the one above) and uploaded it here. If you've already installed the custom template, remove it first. Then, copy the unzipped folder of this new template to the WebExport template folder as discussed above and follow the steps. I created three different types of actions for images (in the export template): images, formulas, and tables. For instance, if all the images in your Ulysses project are formulas, then you can simply assign the "Formula" style action to the Inline Style for images and should get the same output as in the screenshot.

Tut uns Leid, aber das konnten wir nicht wissen :-) Dafür gibt es aber auch ein Deutschsprachiges Forum, schon gesehen?

Herzliche Grüße Vivien

Okay, I found two problems:
Here is one xhtml file from the epub document. And as You can see, there is a title of the chapter and the title of the image. But where can I define these titles?

Where can I define the chapter title, I want to have it in german e.g.:

And where can I define the title of images? I want to have it in german, and I want have other text like "Tabelle" or "Formel":

Can I change it only in the template files and not in Ulysses itself? I need "Abbildung…", "Formel…" and "Tabelle…" within the same document.

I'm a bit confused. Does the custom template not work for you? This should contain exactly these three types. If you use that template, you don't need to change anything in the template files, just select them as an action for the inline style:

If you want to use all three types, you need to create an Inline Style for each type to distinguish between them and then assign each Style its corresponding action in the exporter.
