An illustration can survive translation while the relationship around it breaks. A caption may move away from the image, a reference may point to the wrong figure, or lettering inside the artwork may remain in the source language. Check those as separate questions.
Keep the original EPUB for comparison. Its existing image size, placement, and text arrangement establish what was present before processing.
Separate the image from the text inside it
Captions and in-image labels may be stored differently within an EPUB. Review them separately alongside figure numbers and text descriptions to ensure readers can locate the right image and understand what each part represents.
Before submission, inspect a representative diagram or illustration. Identify which information is body text, caption text, and artwork. If the artwork contains a plot clue, a labeled axis, or instructions needed to understand the page, keep the original available during reading.
When translating an EPUB, PDF Craft aims to preserve images and reading structure. After downloading, you can flip to an image-heavy chapter first to see whether pictures align with nearby paragraphs and captions before reading through the rest of the book.
Check captions as part of the explanation
After download, compare a figure number, its caption, and the sentence that refers to it. The words can read well individually while naming the wrong figure or reversing the relationship described.
For example, in a hypothetical chart with two lines, check whether the caption still identifies which one represents the baseline. For a novel illustration, verify that the caption or nearby text remains associated with the intended scene.
If a caption contains a specialist term, compare its treatment with the body. A consistent preference in the instructions can help communicate the intended wording, but it does not remove the need to inspect important occurrences.
Judge relative position rather than printed pages
A reflowable EPUB changes pagination when font size, screen width, or language length changes. An image appearing on a different screen is not by itself a failure. The more useful question is whether it remains in a sensible relationship to its caption and surrounding passage.
Check just before and after the illustration. Is a sentence cut off? Does the caption appear twice? Has an image inserted between a source paragraph and its translation made bilingual reading confusing?
Test a long passage around an image, not just a full-page illustration. Text expansion is more likely to reveal awkward spacing in mixed content. For wider structural checks, use the EPUB format guide.
Compare display settings and readers
Open the downloaded EPUB at your normal font size and in the appearance mode you use. Inspect image scaling, caption contrast, and the ability to read small labels. If zooming is necessary, check that it works in your actual app.
Try the same location in another compatible reader when an image is clipped, missing, or unexpectedly stretched. Compare the source in both readers too. That distinguishes a source problem, an output problem, and reader-specific behavior more effectively than repeatedly downloading the book.
| Symptom | First comparison |
|---|---|
| Image absent everywhere | Source resource and the downloaded output |
| Image clipped in one app | Same file in another reader and its display settings |
| Caption differs from body wording | Source meaning, figure reference, and term preference |
| Lettering remains untranslated | Whether the text is embedded in the image |
Keep useful issue notes
Record the chapter, figure number, caption phrase, and what differs. Page numbers are less portable across reflowable readers. Keep the downloaded result unchanged while investigating, and edit only a working copy if an external repair is appropriate.
If a file displays formatting issues or fails to open in your e-reader, consult EPUB troubleshooting. When reviewing mixed text and images, confirm that pictures load completely in the right positions, and check captions and text references against the original illustrations.
To start a translation, use the EPUB translator, choose the target language and output, and download the completed task. Translation is charged by usage, with trial credits for new users; current rates are on Pricing. Keep the original alongside the reading edition so visual details remain easy to verify.
