How test if an image (id) still exists before inserting
Hello,
I will have to review 500 images of which one third is not correct.
In order not to go over all the articles, and to modify the insertions of these bad images, I would like to test if an image id still exists before inserting it in an article. A kind of <txp:if_image> …
I think to use <txp:evaluate> on <txp:image id = "..."> but I don’t see how, and if is there a simpler solution?

How about a big list of image tags with a lo-fi table wrapper? Untested:
<table>
<tr>
<td>1</td><td><txp:image id="1" /></td>
<td>2</td><td><txp:image id="2" /></td>
<td>3</td><td><txp:image id="3" /></td>
<td>4</td><td><txp:image id="4" /></td>
</tr>

Re: How test if an image (id) still exists before inserting
Thank you for your answers.
@gaekwad I think I did not express myself well: The images are already introduced in the articles. I need to delete more than 100. How to make the display of a deleted image does not cause an error? The images are introduced by the article_image field. I would not have to go through all the articles to remove the IDs of the deleted images.
—> if_image_exist(“32”) then display it else do nothing.
@colak : fine, this way no error ! Thanks !

If the above works, here’s another way that you can call the custom_field
<txp:images id='<txp:custom_field name="article_image" />'>
<txp:image />
